should have used mining rigs...at least they would have served a purpose other than eating electricity and dust. Or folding at home, or Seti@home, etc...
Fishmonger ! No cuz then ppl would nag that the results are not based on real world results... Because I haven't seen any modern PC that runs 4 gpus pinned at 100% 24/7, thus ramping up the fans
I haven't seen any modern PC's sit for a while in a construction zone either. Fact remains, everyone's house where their PC is will be different, so everyone's results will vary. The most important thing is how each case compares to each other - so it doesn't really matter what they were doing compared to what you do, just that what they do compare to each other equally.
@@b6.b1zz actually you need to make sure you're in an open area preferably not in the same room your PC is going to be in. Also using alcohol wipes can decay some of the plastic in the PC. Dry electronic wipes are a better option. There are so many small things he may not know too like not letting the compressed air blow your fans so you should hold them still. Etc etc.
@@b6.b1zz right, but you may know that but not everyone does. Some people like to be careful and safe with their PCs so this man just wanted to know something he didn't know.
@@DevilMayCare4 Knowledge is power, glad you helped this guy out and didn't be an arse about it, glad there is still some decent people in these comment sections.
On a deployment to Iraq, I noticed that all the computers cpu fans in a high pitch whine. So I open one and there was a literal single blanket of dust bunnies on top of heat sink with thickness limited only by the distance between the cpu fan and heat sink. Along with this a think layer of dust covered everything inside. I took a pair of tweezers to remove the blanket. After going through 2 cans of compressed air, I went to hospital maintenance for a portable compressed air tank. After about 30 min of work that one was clean. It turns out the other 17 units were in the same shape. I don't know how they survived in that condition. After the cleaning I found that the common use computers had multiple user profiles from previous rotation, so I had to clean that mess afterward. You can imagine how bad they were. I just wish I had photos to show you.
Well, you were literally in Satan's armpit. All that's needed to cure this is a dunk in the Tigris (or Euphrates), a box of grid squares, and an exorcism.
One thing not mentioned in this is volume of airflow. On the "In betweenie" there appeared to be a lot more dust in the filters than the filters belonging to "Innie". I think this is because of the increased airflow allowed by the balanced system in the case. This means that you might get more dust, but you also get more air flow, and therefore a cooler running system.
Interesting video but my 2 cents maybe 3. I have been supporting small business systems for over 13 years and I have noticed that if you keep the system off the floor the dust build up is “low” compared to on floor systems. Get the system 2 feet off the floor and different is amazing. I have also noticed that carpeted offices are very bad for build up if the system is on the floor. The worst site I ever had was an equipment rental store that also sold ready mix concrete in the small trailers that you tow behind your truck and spill on road when you accelerate too fast. I would have to clean the cement dust out every 6 months and in some systems there would be 1/8” of dust on the bottom of the inside of the cases. I moved them up to the 2nd shelf under the counter and lost a maintenance revenue stream.
Thats why you need to put your guys on a monthly fee. But yeah, IT for 8 years, I noticed same thing. He puts the computer on the desk or else he gets the hose again. air hose
I work in the agricultural industry and dust or dirt is what we work in and is also what we have to keep out. Yes elevation works. the larger particles get kicked up easier but don't float as high. The best solution is positive filtered case pressure. More filtered air going in than unfiltered exiting. This will put a positive case pressure keeping out unfiltered air out. This even will account for seems in the case. Take those filters out every now and then to clean or replace. This will make a huge difference.
Working as a computer tech I'll say this: smokers have by FAR, the most disgusting machines you could imagine. I remember one in particular, open the side panel and the whiff of tar would hit you like a truck...I started unscrewing the CPU heatsink to change the paste,1,2,3,4 screws off yet the heatsink is still not coming off? What the hell? Turned out the heatsink was actually glued to the motherboard by dried tobacco/cannabis tar.Had to push and pull the heatsink from both sides at the same time lol so gross
Yep, can confirm. Worked as a bench tech for a couple years and smoker-owned machines ranged from "meh" to "HOLY SHIT". Little brown ghost turds that smell like straight death. That shit is nasty.
@Egon Freeman Yeah, I can tell you most people have the simplest, smallest old pc's with basically no airflow...I wish we could upload attachments to comments, I would have put it, like a thick crust of god knows what substance built up between the heatsink and the fan, fucking grooossss. Left it running overnight, came back to the shop in the morning, the whole place smelled of death lmao
He mentioned at the start, which one is still working... Then didn't say if one broke or not. Guessing that means they all work, so temps would have been good. I feel they phoned this one in.
Those were just qualitative tests, they can't give any accurate answers. Quantitative tests like Temperature would give us real results. I wonder why they didn't do it. They always show this kind of results in the benchmark videos.
One problem with this experiment is the type of dust. Living environments have stickier debris and dust. Skin cells partially digested by fungi, body oils, water from your breath, etc.
I'm shocked this isn't really talked about here. Living environments have dust is as you say, plus a tonne of fabrics (carpet, clothes, curtains, bedding) all giving off micro fibres they're used, plus normal house activity bringing in all kinds of particles that are quite different to 'construction' particles which are more like fine dirt, not oily skin and fabric particles.
All of that is in the warehouse and offices too...maybe minus kitchen grease but with added construction mess. That's why they mostly looked whiteish...drywall takes over everything.
@@yourhandlehere1 this. I know it has been 5 months but this is the most important factor. Cooking vapors, be it water or general grease, makes all the dust already accumulated in your computer to "glue" together, forming that THICC mesh of dust, like a fabric really. In the office, you get a nice air conditioning (mostly filtered, dry air), closed doors etc, way different environments. Dude, sometimes I'm cooking and can even feel on my skin the fat/water accumulated after a while, imagine what your pc feels after a few months.
Always have 1 more fan (filtered) blowing air into the case than out. That way you create positive pressure. And because your case has a lot of crevices you cannot really seal, its better to push clean out through those crevices, than pull unfiltered, dirty air in. Then: Clean your filter frequently! The dirtier it is, the more sucking force will be applied by the fan eventually forcing dust through the filter (which otherwise wouldve been stuck in the filter).
I'm in the positive pressure camp myself for the reasons you explained, but I only have two sys_fan headers on my cheap little B450M and I wouldn't mind getting your opinion on something. Case came with two 120mm fans, one filtered intake in the center of the front panel and one exhaust on the top of the rear side. Wanted to get another intake for the 120mm mount under the front intake, but the cooling has actually been fine, I don't do any OCing on my 3600 other than XMP. I still plan to study up on fan splitters and will probably get a second intake at some point, but in the meantime, I've been using curves to run the intake a little harder (in DC mode; case fans are only 3-pin sadly) to account for the intake filter and hopefully at least get some slightly-positive pressure. I had the intake fan set to +0.6v higher than the exhaust, this past week I've widened that gap to 1.2v. So at, say, 40c, the intake is running on 7.2v and the exhaust is on 6.0v. Dumb idea, or good enough as a short-term solution until I decide on a fan splitter? FWIW this seems to give me a pretty consistent extra ~120 RPM on the intake compared to the exhaust according to hwinfo, but I dunno to what degree that extra pressure is offset by the filter. It's tricky to find info on setting intake/exhausts to different voltages/speeds, Google usually just gives me a ton of articles explaining the difference between PWM and DC 🤦♂
I'd like to see what I could do to murder a machine but within strict guidelines of not just booting the thing around. All tech based and reasonable options to threaten and kill it so it would have to be a planned and structured way of punishing, abusing and compromising a CPU or GPU and just throw everything at it to kill it.
Try using an air purifier system, with an ionizer option if you want, for $40-$80 in the room with your PC and you can reduce your dust quite a bit. I've never used a mini-sized or desktop ones, but the taller $80 versions work good. We have one in our living room as well and its amazing how much less dust we have to clean off of our electronics and shelves. As someone who isn't a clean freak, I just enjoy not having to clean as much in general.
Christian Stout they make hepa cases that you put your computer case in and they pull large amounts of air through an AC grade filter Ive seen them used more and more in shops and factories with the rise of graphically intensive equipment like optical measurement systems
I have had a silverstone ft02b since 2009 and only clean the filters a few times a year. The inside is still pretty clean and the only hardware I have changed since 2011 is my graphics card. Best case ever IMO. 3 180mm fans on the bottom blowing straight up (filtered) and the power supply blowing straight up (filtered). Positive air pressure, so there is nothing getting sucked in the drive spaces, etc. No idea what I would replace this case with.
Isn't it strange that for the past 1 year every day of my life I have been thinking about those computers sitting behind that wall living without much of a purpose.
Its kinda hard to say if all out or all in is better without doing a real test. With all out, it would almost be like a passively cooled case, which those tend to perform fairly well. But on the other hand I think theoretically all in would do better... Most of that air being brought in is going to just circle around trapped and turn into warm air, but theres still a constant cool air intake to keep it from getting hot.
I know its been a very long time since video but I'd love to see a follow up where you investigate the cooling capabilities of these 3 configurations and come to a conclusion about what is the best dust collection to cooling performance ratio
When Linus says "It really makes me wonder how people get their computers disgutsting enough ect.." In my experience its from smokers. Smoke when laying around in the air, will collect on any surface it touches making something called "resin". Just like tree resin or sap, its very, VERY sticky, and dust, pet hair, dander, all stick WAAY more, than even in the worst case scenario, like a construction site. Unless all of the construction workers smoked like Bill Hicks.
In my experience, its from people with no clue about computers + let us be honest, most average pc users dont have full dust filter setup. Opening my sisters pc after at least 5 years without cleaning or dust filters (she is that kinda person that doesnt even know you could open a pc case) i was in more than a shock. We're talking partially almost an inch of dust buildup, a family of over 10 spiders living in it etc etc.. I really would have wanted to see the video, but with dust filter-less PC.
Its not just smoke but that is bad on them. Pet hair and thick carpeting will make a mess too. Even the area you live in and how well the air quality in your house is. Mold is another big one. Also most really dirty computers didn't get that way in a year. They were used for years and years and never cleaned or taken apart. That being said I have seen computers six months old with a smoker look worse than those.
For the amount of time you had, I expected for quantitative results. What are thermals like? What is the air pressure inside the case before and after? Etc.
Yeah, something more than just : "Oh look they're all dusty..." No shit Sherlock. How about some actual effort and some usable values. Could have done much more.
nappydrew they made a big deal about how much work it was going to be to make a video about it, and delayed the results. This seems like it took 15 minutes not including editing, so I think they could have managed 3 months ago.
I'm sure they would have been the same but still would have been nice to see the info, plus there is always the possibility they wouldn't have been the same but now we will never know.
No they wouldn't I took an engineers computer where i work and cleaned it out cuz the cpu was throttling hard. It went from easily hitting 70C to barely hitting 63C on a stress test
Warehouses with lots of people produce more dust than a bedroom. We have to brush our warehouse out weekly to keep it clean from mud and general debris from dozens of people walking through it. Remember carpets aren't dusty they simply hold dust. So wash your carpet and it won't be a problem for a while.
Get a metal frame that holds your PC off the ground a little bit. Most cases come with them, or you can just prop it up a little bit with a couple pieces of wood or something, and make sure your power supply fan is exhausting. You for sure don't wanna have it directly on carpet.
Yup, I had an old PC before that I kept about 2 inches above the carpet and man, it got almost as bad as these PCs in the span of 6 months. Also the case kind of sucked so that could've contributed. Now I have a new improved rig on top of a glass desk 3" ft high with tile flooring...and the difference is remarkable. After 4 months the dust is about a fifth of what it used to be compared to my old pc.
After I upgraded my fans for more air flow and went from 2 in 3 out to 4 in 3 out, my dust build-up dramatically decreased. Might have something to do with the 2 extra intake fan slots having no filter, so dust was lightly being pulled in and settling, but now the slight positive pressure and higher rate of air flow keeps it from settling as easily. Most of my dust build up is on my outtake radiator and on the outside of my outtake fans, but even then, I can go 6 months with little to clean from those parts in my dry climate.
Those mesh filters dont filter anything if you want to keep all dust out of a pc buy the filters that go on ac units the black stuff that looks like foam I use that on my pc and a year later just a small layer of dust and that is with all the fans at full speed all the time
sounds weird choice to produce those units with dark color. are you sure that those are air filters and not the ones that are used to remove odors with active carbon?
I live on a dirt road,cleaning out my computers is a every 6 month thing.what you can get from this video is no matter how you flow the air you need to clean it.
I hardly need to clean my PC even though the pollution of my country is pretty bad because I have positive air pressure (most of the fans blowing inside the case with filters outside). I actually have not cleaned my PC at all for 6 years. I only need to replace the 3M filters (for air conditioner).
A little late to the party, but: a) should've done thermals first! b) blowing air in without filter doesn't reduce the amount of dust inside. Who would've thought?
@@wadez1000 lmfao. for real tho computers shouldn't "die" if treated properly and are quality products. this mentality is kind of detrimental as people think old technology is useless when in fact its still very much useful. We need to change this way of thinking or E-waste will continue to increase and technology will become the new gas in terms of global warming.
I have a fancy case, but it still collect a ton of dust in a matter of a month. That's because it's situated on the first floor near a window and my building is near a road. I'm probably dying right now from the amount of dust I have in my room, lol.
true my default computer case that came with the set up when I bought my computer 4k computer by the way 10 years ago came with no filters and only a single exhaust fan.
I feel like it has been like 5 years since the last video, just because there is so much change going on in my life and so many things happened. This video made me realise how much stuff can happen over the course of one year. It's actually amazing
Omg i remember you uploading that vid thinking 'dam i need to wait a year'. Today is the first time watching the follow up....3 years later, fuck time goes so fast man
linus, we all appreciate when you are genuinely excited about something, not when you are trying to be excited to boost theoretical viewability of the video
Wellbeserious.......you still have all the same components that are affected by dust like the cpu, graphics card and power supply. Dust doesn't affect the board that much. From this I can see that a case with great filters would work best.
These computers aren't dusty because of the constant running. A persons average computer is dusty because the constant on and off again, feed dust and letting it settle inside where the fans cant blow it away
I JUST put 5 new static pressure optimized case fans into my case last week, so great timing with this video! I have all five fans as intake based on an older video where Linus recommended that setup to mitigate dust buildup. However, I see that there's really no "hands-off" fan configuration. I will clean my dust filters every month and take some canned air to the interior just to be safe. *EDIT* Thank you for the suggestions everyone! I've changed the rear fan to exhaust so I still have positive pressure in addition to moving hot air out actively instead of just pulling in cool air.
SP fans are designed to overcome resistance - if the case is restrictive in some way (fine meshes, air filters, grilled etc.) then they may well have been the better choice.
you can use better filters and cover all holes on your case with them but then you'll still have to clean those filters. Btw, no need to clean your case every month. Twice a year is fine unless you got your PC in seriously dusty place.
jared varner It’s cryptocurrency. Nobody should generalise crypto as btc as they are majorly different. If you are complaining about something, at least know the facts
A couple years later, I have a new thing you could test. You tested in, out, and in between. Can you test "flow" oriented cases [like servers]? I'm referring to cases where the air is meant to come in the front, go out the back, and with no openings in between, like a wind tunnel. And since the context is servers, you could probably test high fan speeds, medium speeds, and low speeds.
I remember cleaning my very first PC after using it for 6, 7 years, what a gory sight that was. I only cleaned it as it started to turn off due to overheating. (Didn't know much about PCs back then)
One thing I've found is that when I go to homes where the client smokes, I find a lot more dust sticks in the computer. It's even harder to wipe off, because the smoke residue creates a slightly sticky layer on everything.
Smoker here, can confirm. Nicotine sticks to everything and makes everything sticky with a thin yellow layer of nicotine (including your white ceilings and walls, which won't be white for long). Not good.
Confirmed, my mom is a 40 year smoker, and has wood heat. I have to go clean her PC at least once every 3 months, it's awful :( Good news she is moving and will be quitting smoking, and no more wood heat! Yay!
I suspect there's a lesson here which no one caught: Outtie was pulling a decent amount of air from the big filter on bottom, sure, and also a bit from other areas. What this means, though, is the pressure near the intake areas was probably lower on outtie than it was on innie, and I suspect that as a result, _less total dust_ was being pulled into the case to begin with. Sure, the dust particles are light, but they're definitely heavier than air, and they're definitely not going to respond to changes in air pressure and air flow the same way that air is going to. I suspect a further test that could add valuable data would be to repeat outtie, but leave all the filtered intakes with no fans, and cover over any unfiltered holes in the case with tape to seal it up everywhere else. I suspect that would result in the lowest amount of dust.
Something I wonder is if a fan will pull more dust through a filter than a very steady, equivalent air flow. Because although the total air flow would be the same, the fans are essentially beating air through the filter, while the bottom filter on the outtie, for example, has a much gentler and more consistent flow, with the same net movement of air. Might this make a difference?
I really appreciate this test. That being said, you should obviously have filters on all intakes. I bet Innie would look fine with filters on everything.
I thought my house was dust free because after half a year there was literally no dust anywhere. I then put my dust filter on and after just a month I already saw clear circles of dust on the mesh
Unless you have heavy-duty airfilters running in multiple rooms of your house, they're always going to be dust. Your skin and hair, dust brought in from outside, dust from breakdown of materials like carpet and clothing and books... there's just too much going on to keep a house free of dust unless you've go some serious filtration going on.
zeemonkeyman1 No, he’s correct about skin being one of the largest components of dust. Kinda gross to think we all breathe in each others dead skin particles all the time lol.
Another thing this video shows is that the stock case filters are just not good enough. One reason I use those cut to fit A/C filters over all the intakes of my PC fans. More work to replace them but taking the hard work involved in cleaning a dusty and clogged PC, it is worth it.
For a super cheap option, I recommend simply buying panty hose and stretching them over your intake fans. I've had panty hose on my intake fans for the past two years and they catch a ton of dust.
nul, so does literally any filter, technically speaking. Have you ever seen stretched panty hose? They're basically thinner than any filter you'd buy. If you're so worried about potentially losing a degree of coolness because you're using panty hose as a filter, then maybe you're not the target audience for this lifehack. If you're super serious about your temps then you shouldn't be skimping on your cooling and airflow to begin with, and if you are only doing light overclocking at best, one layer of stretched panty hose over each intake fan is fine.
0:19 i didn't watch this for another 10 seconds and thought he actually was fired or something lol. Apparently LMG is building Floatplane, a video streaming service, with Luke leading the program, meaning that while he technically doesn't work for LMG anymore, he'll still be in the building and doing stuff there, just as a part of Floatplane instead.
Ditto. Have a smoking friend with 2 large dogs and a cat. He played games in laptop and smoked and did that in kitchen for 3 years. After that laptop simply died due to overheated mainboard that was literally covered with tobacco tar grease mixed with dust and fur. Primary malfunction cause was GPU which popped off from mainboard. There was nothing to salvage anymore. Now he play his stuff in desktop PC located in another room on table. That build is now much cleaner with occasional dust that is easy to clean.
@@KrotowX there's little more disgusting than tobacco tar grease... especially if the inhabitants of such place don't even clean the most basic surfaces
Those filters don't block enough dust. My case (NZXT Source 210) did not come with filters, but I made my own out of a cheap window air conditioner filter you can buy for a couple dollars. It is probably 3 times as thick as the ones in that case. I put filters over all the intake fans and blocked off every other hole in the case with tape, even little screw holes. After 2 months, my filters have a thick sheet of dust covering them that you can litterally peel off if you want to. The inside stays mostly clean except for some really fine powdered dust that makes it through.
Some people say they don't, some people say they both count as engagement. Who knows? At this point all we know is that youtube is a big black box, a big shamelessly lying black box.
I was referring to the video, hehe :) I only realized it could be interpreted as an attention grabbing comment after I refreshed and it had a ton of likes. Anyway, the important part is to like Luke.
yeah nd the likes incourages the creator to make more and better content, that's the important part! That will have a positive outcome in the long run cuz people will like and subscribe and the channel will keep growing and from there their vids will probably pop up one day on new strangers and they will watch the video and like it.
It looks like the In-Between case had more dust on the fans due to it moving more air through them. Since the intake fans weren't fighting against too much positive pressure inside the case, as they were with the all intake scenario, they could push more air into the case. Also, since they concentrated the intake through the filters rather than just anywhere air could get into the case, as in the all exhaust scenario, the filters appeared dirtier again due to the greater amount of air moved through the case. In all of these scenarios, the GPU and CPU temps of the In-Between setup should have been the lowest, and would just require a little more attention to cleaning the filters as they got dirty.
Yeah, I wished they would have done thermals and benchmarks to see how the performance of the machines were altered by the dust and potential heat issues.
OsDoesCOD Not the results we wanted though. Where are temperature results. How much of a difference was measurably between them. Does that thin film in the balanced system make much difference to all out.
Santa Clause Who knows for sure? That's why they should test it. Cleaning dust out of the case's intake lowered my Pentium D's idle temps by 10°C, an it was looking like the last case in the front, but it has an airduct that pulls in from there, directly onto the CPU.
this was my issue too (still is but i have made it a little better). If it isn’t already, place the pc higher off the ground. maybe at least 2 metres? mine is 3 metres up and it is at least twice better. hope this helps
Firstly I realise it's text. But I thought it was obvious I was joking. Secondly, I have never known even the dustiest PC to short through dust. I've heard the tale before, but I wonder how true it is. I guess it depends on the content, but in the countryside our dust isn't very conductive. Literally measuring resistance with a multimeter of ground (potted plant) 5mm apart and don't get a reading in the dry. So more than 100kOhm. I guess city car fume and such like dirt may be more conductive, but that would be an interesting test. Use a HEPA filtered vacuum to hoover the air in a city for a day around polluted roads (not the floor.) then compare to the countryside. An artist of all people had done this. He made a brick from the dirt in the city. I guess you could test it's conductivity and then know if it's bull it plausible. After all, it's 12V mostly.
I think I posted this before but your dry warehouse dust is a lot different (fine grains) compared to most people's house and specifically bedroom dust where there's carpet, bedding, towels etc, those long fibers really stick across heat sink fins and form dust bunnies etc!
Holy shit i remember watching the setup video like 2 years ago and thought one year was ages away, now here i am remembering that this was even a thing. Time is weird
Just watched this and I must say it's pretty logical. All out produces way less dust inside, the only problem with that is it also provides the least cooling.
Dust from construction is not like typical computer dust. Typical computer dust contains things like human skin, pet dander, smoke, etc all of which are stickier than dry-wall dust. Notice how a lot of the dust is just sort of sat on top of horizontal surfaces instead of stuck all over every single surface.
That's why the inny worked so well I think. The dust was naturally heavy so, coupled with the downwards air flow, it just all settled on the bottom filter without going anywhere else.
After 1 year of bench-marking 3 systems with 3 different air pressure tests, the results are... inconclusive. This however, is not a failed experiment!. Far from it! This actually helps us to better understand that dust enters the system, no mater how you try to avoid it! What we can learn from this is, that having decent filters at ALL vents is important. Whether it's blowing in or out, filtration is key! If you place your system on the floor (which I think the majority of people do still), then the key thing to note from this is: That we should have decent filtration at the bottom of the case, regardless of pressure placement... Gravity is the king-kong of dust problems! From what we saw, top dust seemed to have very little baring on the overall results of the 1 year negative/ positive/ natural air pressures inside the case. Despite there being a lot of construction around the environment for all 3 systems. The bottom filter was key! It makes logical sense right?! When you think more about it: Dust particles are heavy! They don't take long to hit the ground after being air-borne. Those dust particles that miss the case completely, or those that are drawn out, or blown out of the case, EVENTUALLY end up on ...... the FLOOR (under or around the case). So the most important factor is (besides having internal flow ), to ensure you have good circulation (negative or positive), and always blow air away from the side facing the floor :) I hope i didn't upset or undermine anyone in my resonance to this dear Watson(s)! But it seemed like clear deduction.... a process of elimination! Go Linus Tech Tips... and thanks Luke for coming back to conclude this experiment.
well no it was a stupid test, the most common setup recommended is a positive pressure setup with more intake fans than outtake to avoid dust coming in through gaps. But unless all the intakes are filtered that's meaningless. If you don't filter every intake fan you're wasting time in dust prevention.
I have the same case, on the floor, and placed a extra fan on the bottom, its now in from the front and out the back and bottom, so it doesnt suck any dust in from the bottom. I will just have to see how it looks in a couple of weeks :)
Because it all depends! PC enthusiasts love to constantly fight over what's better with anything PC related, while at the end of the day it always depends. That's kind of the point of this video series, lmao.
If you guys had every been in a factory setting (especially a textile mill), you'd see some serious dust-covered PC's. Where I work, if I just lay my phone on a flat surface out on the production floor, the screen would be completely covered within an hour. The computers there run 24/7-365. The one I've been using has been there at least 6 years in that environment and I have no clue when the last time they were powered down, much less cleaned.
@@uni4rm Well I've never smoked anything in my life and, up until recently when they were all confiscated, I wore an N95 mask any time I'm on the production floor.
A shorter temperature test, for a few hours, should be enough to compare the systems' cooling performances. IIRC Luke made a video comparing airflow setups in 2015.
Open Case Master Race reporting in. Ironically enough, I have actually experienced less dust build up with the main/side panel off than I have with it on.
If you have a good fan configuration and set up the air will move faster through the case. With the side panel off you do not really have an airflow. If your fan configuration and set up is bad it will not make much difference. There are enough tests out there proving the point. If you have better cooling with the side pannel off it means that you need a better case or just improve the airflow.
Great testing nice to see the differences, my passing thought was, as much air in on the front, then out on the top, bottom and rear. Example on this case. Air in at the front to maintain a fresh clean supply (2x fans), Out on the bottom with 1x fan near PSU that should cover the graphics card and psu, I’d also put tights over the the bottom filter where the fan isn’t installed. The top and rear should be outs 3x fan’s, this should maintain the negative air around the cpu and ram.
Wow! A year flies by so quickly. It feels like it has only been 15 months since the first video!
guess what????

only on linus tech tips would leave 3 computers working for a whole year only to see how much dust it collects.

Fishmonger ! No cuz then ppl would nag that the results are not based on real world results... Because I haven't seen any modern PC that runs 4 gpus pinned at 100% 24/7, thus ramping up the fans
One... more... year!
I haven't seen any modern PC's sit for a while in a construction zone either.
Fact remains, everyone's house where their PC is will be different, so everyone's results will vary.
The most important thing is how each case compares to each other - so it doesn't really matter what they were doing compared to what you do, just that what they do compare to each other equally.

On a deployment to Iraq, I noticed that all the computers cpu fans in a high pitch whine. So I open one and there was a literal single blanket of dust bunnies on top of heat sink with thickness limited only by the distance between the cpu fan and heat sink. Along with this a think layer of dust covered everything inside. I took a pair of tweezers to remove the blanket. After going through 2 cans of compressed air, I went to hospital maintenance for a portable compressed air tank. After about 30 min of work that one was clean. It turns out the other 17 units were in the same shape. I don't know how they survived in that condition.
After the cleaning I found that the common use computers had multiple user profiles from previous rotation, so I had to clean that mess afterward. You can imagine how bad they were.
I just wish I had photos to show you.
Wtf
Well it doesn't surprise me, it's like the average office except 10x more dusty
Well, you were literally in Satan's armpit. All that's needed to cure this is a dunk in the Tigris (or Euphrates), a box of grid squares, and an exorcism.
Thank you for your service. God bless.
Any clue of fans direction and filters?
One thing not mentioned in this is volume of airflow. On the "In betweenie" there appeared to be a lot more dust in the filters than the filters belonging to "Innie". I think this is because of the increased airflow allowed by the balanced system in the case. This means that you might get more dust, but you also get more air flow, and therefore a cooler running system.
It also helps that all intakes are filtered, unlike the other two systems.

Interesting video but my 2 cents maybe 3.
I have been supporting small business systems for over 13 years and I have noticed that if you keep the system off the floor the dust build up is “low” compared to on floor systems. Get the system 2 feet off the floor and different is amazing. I have also noticed that carpeted offices are very bad for build up if the system is on the floor. The worst site I ever had was an equipment rental store that also sold ready mix concrete in the small trailers that you tow behind your truck and spill on road when you accelerate too fast. I would have to clean the cement dust out every 6 months and in some systems there would be 1/8” of dust on the bottom of the inside of the cases. I moved them up to the 2nd shelf under the counter and lost a maintenance revenue stream.
You should get more likes! This is probably the best insight I've read here. Thx!
Last words gave me a smile:)
Maybe that's why a lot of IT services don't bother about dust collection-dust cleaning revenue
Thats why you need to put your guys on a monthly fee. But yeah, IT for 8 years, I noticed same thing. He puts the computer on the desk or else he gets the hose again. air hose
Alright, I've got it. Lie to the customer.
I work in the agricultural industry and dust or dirt is what we work in and is also what we have to keep out. Yes elevation works. the larger particles get kicked up easier but don't float as high.
The best solution is positive filtered case pressure. More filtered air going in than unfiltered exiting. This will put a positive case pressure keeping out unfiltered air out. This even will account for seems in the case. Take those filters out every now and then to clean or replace. This will make a huge difference.
Working as a computer tech I'll say this: smokers have by FAR, the most disgusting machines you could imagine.
I remember one in particular, open the side panel and the whiff of tar would hit you like a truck...I started unscrewing the CPU heatsink to change the paste,1,2,3,4 screws off yet the heatsink is still not coming off? What the hell?
Turned out the heatsink was actually glued to the motherboard by dried tobacco/cannabis tar.Had to push and pull the heatsink from both sides at the same time lol so gross
i bought a gpu from someone that smoked, forgot people still did that in their houses. it smelled for like a month.
Yep, can confirm. Worked as a bench tech for a couple years and smoker-owned machines ranged from "meh" to "HOLY SHIT". Little brown ghost turds that smell like straight death. That shit is nasty.
Yea if you're smoking in the same room with your computer all day long you aren't doing it any favors.
@Egon Freeman Yeah, I can tell you most people have the simplest, smallest old pc's with basically no airflow...I wish we could upload attachments to comments, I would have put it, like a thick crust of god knows what substance built up between the heatsink and the fan, fucking grooossss.
Left it running overnight, came back to the shop in the morning, the whole place smelled of death lmao
now imagine the lungs of a smoker
I think that a temperature test will tell more than dust in the GPU
Enrique Davila that's what I thought they would do as well... Kind of sucked that this video was kind of forgotten about over the year.
He mentioned at the start, which one is still working... Then didn't say if one broke or not. Guessing that means they all work, so temps would have been good.
I feel they phoned this one in.
Those were just qualitative tests, they can't give any accurate answers. Quantitative tests like Temperature would give us real results. I wonder why they didn't do it. They always show this kind of results in the benchmark videos.
Renato Avilez seems like they started this experiment and got everyone hyped and then just didn't wanna bother with it after that
They didn't show the GPU fans/heatsinks but I don't think there was enough dust buildup on the CPUs or mobo's to affect temps at all.

One problem with this experiment is the type of dust. Living environments have stickier debris and dust. Skin cells partially digested by fungi, body oils, water from your breath, etc.
I'm shocked this isn't really talked about here. Living environments have dust is as you say, plus a tonne of fabrics (carpet, clothes, curtains, bedding) all giving off micro fibres they're used, plus normal house activity bringing in all kinds of particles that are quite different to 'construction' particles which are more like fine dirt, not oily skin and fabric particles.
Not to mention a lot of people have pets, which would make the situation a lot different lol
I was eating...
*Was*
All of that is in the warehouse and offices too...maybe minus kitchen grease but with added construction mess. That's why they mostly looked whiteish...drywall takes over everything.
@@yourhandlehere1 this. I know it has been 5 months but this is the most important factor. Cooking vapors, be it water or general grease, makes all the dust already accumulated in your computer to "glue" together, forming that THICC mesh of dust, like a fabric really. In the office, you get a nice air conditioning (mostly filtered, dry air), closed doors etc, way different environments. Dude, sometimes I'm cooking and can even feel on my skin the fat/water accumulated after a while, imagine what your pc feels after a few months.
Always have 1 more fan (filtered) blowing air into the case than out. That way you create positive pressure. And because your case has a lot of crevices you cannot really seal, its better to push clean out through those crevices, than pull unfiltered, dirty air in.
Then: Clean your filter frequently! The dirtier it is, the more sucking force will be applied by the fan eventually forcing dust through the filter (which otherwise wouldve been stuck in the filter).
I'm in the positive pressure camp myself for the reasons you explained, but I only have two sys_fan headers on my cheap little B450M and I wouldn't mind getting your opinion on something. Case came with two 120mm fans, one filtered intake in the center of the front panel and one exhaust on the top of the rear side. Wanted to get another intake for the 120mm mount under the front intake, but the cooling has actually been fine, I don't do any OCing on my 3600 other than XMP.
I still plan to study up on fan splitters and will probably get a second intake at some point, but in the meantime, I've been using curves to run the intake a little harder (in DC mode; case fans are only 3-pin sadly) to account for the intake filter and hopefully at least get some slightly-positive pressure. I had the intake fan set to +0.6v higher than the exhaust, this past week I've widened that gap to 1.2v. So at, say, 40c, the intake is running on 7.2v and the exhaust is on 6.0v. Dumb idea, or good enough as a short-term solution until I decide on a fan splitter? FWIW this seems to give me a pretty consistent extra ~120 RPM on the intake compared to the exhaust according to hwinfo, but I dunno to what degree that extra pressure is offset by the filter. It's tricky to find info on setting intake/exhausts to different voltages/speeds, Google usually just gives me a ton of articles explaining the difference between PWM and DC

Drag your feet on the rug and tease you'll touch it!
Why
Brings a new meaning to something just "sitting there gathering dust"
Cont3mplation like what glados says
Try using an air purifier system, with an ionizer option if you want, for $40-$80 in the room with your PC and you can reduce your dust quite a bit. I've never used a mini-sized or desktop ones, but the taller $80 versions work good. We have one in our living room as well and its amazing how much less dust we have to clean off of our electronics and shelves. As someone who isn't a clean freak, I just enjoy not having to clean as much in general.
What I'm getting from this is that I need to submerge my PC in mineral oil to completely eliminate dust.
Luckily there is a tutorial for this highly reasonable plan on the channel.
Christian Stout they make hepa cases that you put your computer case in and they pull large amounts of air through an AC grade filter
Ive seen them used more and more in shops and factories with the rise of graphically intensive equipment like optical measurement systems
I have had a silverstone ft02b since 2009 and only clean the filters a few times a year. The inside is still pretty clean and the only hardware I have changed since 2011 is my graphics card. Best case ever IMO.
3 180mm fans on the bottom blowing straight up (filtered) and the power supply blowing straight up (filtered). Positive air pressure, so there is nothing getting sucked in the drive spaces, etc.
No idea what I would replace this case with.
@@AsbestosMuffins r/whoooooosh
Christian Stout i
Isn't it strange that for the past 1 year every day of my life I have been thinking about those computers sitting behind that wall living without much of a purpose.
also if they kept them in places where people are and not in hidden room they would probadly have much more dust
They had a purpose now. Clean the air
They had purpose this video
Benchmark with temps!!!
please!
ZeuxDar I also miss that part
Without temps people are like oh all out is great. But it isn't, it is maybe good for dust but not for your temps
Its kinda hard to say if all out or all in is better without doing a real test. With all out, it would almost be like a passively cooled case, which those tend to perform fairly well. But on the other hand I think theoretically all in would do better... Most of that air being brought in is going to just circle around trapped and turn into warm air, but theres still a constant cool air intake to keep it from getting hot.
I know its been a very long time since video but I'd love to see a follow up where you investigate the cooling capabilities of these 3 configurations and come to a conclusion about what is the best dust collection to cooling performance ratio
Pff amateurs, today I cleaned my case coolers the first time in 5 years. Didnt even knew I had LED's on them since I didnt see them for years...

When Linus says "It really makes me wonder how people get their computers disgutsting enough ect.." In my experience its from smokers. Smoke when laying around in the air, will collect on any surface it touches making something called "resin". Just like tree resin or sap, its very, VERY sticky, and dust, pet hair, dander, all stick WAAY more, than even in the worst case scenario, like a construction site. Unless all of the construction workers smoked like Bill Hicks.
In my experience, its from people with no clue about computers + let us be honest, most average pc users dont have full dust filter setup. Opening my sisters pc after at least 5 years without cleaning or dust filters (she is that kinda person that doesnt even know you could open a pc case) i was in more than a shock. We're talking partially almost an inch of dust buildup, a family of over 10 spiders living in it etc etc.. I really would have wanted to see the video, but with dust filter-less PC.
Its not just smoke but that is bad on them. Pet hair and thick carpeting will make a mess too. Even the area you live in and how well the air quality in your house is. Mold is another big one. Also most really dirty computers didn't get that way in a year. They were used for years and years and never cleaned or taken apart. That being said I have seen computers six months old with a smoker look worse than those.
Luke laughing when sponsors come out lmao
thinking: "I didn't miss this"
For the amount of time you had, I expected for quantitative results. What are thermals like? What is the air pressure inside the case before and after? Etc.
Yeah, something more than just : "Oh look they're all dusty..." No shit Sherlock. How about some actual effort and some usable values. Could have done much more.
nappydrew they made a big deal about how much work it was going to be to make a video about it, and delayed the results. This seems like it took 15 minutes not including editing, so I think they could have managed 3 months ago.
Temps would have been exactly the same, you can test that on your own system
I'm sure they would have been the same but still would have been nice to see the info, plus there is always the possibility they wouldn't have been the same but now we will never know.
No they wouldn't I took an engineers computer where i work and cleaned it out cuz the cpu was throttling hard. It went from easily hitting 70C to barely hitting 63C on a stress test
One thing that helped these keep down on the amount of dust is the lack of carpeting. Houses with carpet almost always have more dust.
forgotn1 I have my pc in my bedroom (on carpet) soooo... What they have dust wise is like 3 or 4 month for me xD
Warehouses with lots of people produce more dust than a bedroom.
We have to brush our warehouse out weekly to keep it clean from mud and general debris from dozens of people walking through it.
Remember carpets aren't dusty they simply hold dust.
So wash your carpet and it won't be a problem for a while.
Mark Pearce Don't most big warehouses have air filtering? (Filtering dust out of the air)
Get a metal frame that holds your PC off the ground a little bit. Most cases come with them, or you can just prop it up a little bit with a couple pieces of wood or something, and make sure your power supply fan is exhausting. You for sure don't wanna have it directly on carpet.
Yup, I had an old PC before that I kept about 2 inches above the carpet and man, it got almost as bad as these PCs in the span of 6 months. Also the case kind of sucked so that could've contributed.
Now I have a new improved rig on top of a glass desk 3" ft high with tile flooring...and the difference is remarkable. After 4 months the dust is about a fifth of what it used to be compared to my old pc.
After I upgraded my fans for more air flow and went from 2 in 3 out to 4 in 3 out, my dust build-up dramatically decreased. Might have something to do with the 2 extra intake fan slots having no filter, so dust was lightly being pulled in and settling, but now the slight positive pressure and higher rate of air flow keeps it from settling as easily. Most of my dust build up is on my outtake radiator and on the outside of my outtake fans, but even then, I can go 6 months with little to clean from those parts in my dry climate.
*Filters are good, and maximum airflow is good.*
appollo 13 reference?
Those mesh filters dont filter anything if you want to keep all dust out of a pc buy the filters that go on ac units the black stuff that looks like foam I use that on my pc and a year later just a small layer of dust and that is with all the fans at full speed all the time
This is truth. also WAY cheaper than "PC" case filters.
sounds weird choice to produce those units with dark color. are you sure that those are air filters and not the ones that are used to remove odors with active carbon?
Clean the dust filters every few months.
Vacuum is okay, wash and scrub is better if an option.

mbsnyderc have you tried living in a house?
I hardly need to clean my PC even though the pollution of my country is pretty bad because I have positive air pressure (most of the fans blowing inside the case with filters outside). I actually have not cleaned my PC at all for 6 years. I only need to replace the 3M filters (for air conditioner).

Get an mini/smaller-than-ITX then for lower dust impact.
Wellbeserious.......you still have all the same components that are affected by dust like the cpu, graphics card and power supply. Dust doesn't affect the board that much. From this I can see that a case with great filters would work best.
Many completely/mostly closed micro/whatever form factors are more resilient than most form factors, but lower performance.
These computers aren't dusty because of the constant running. A persons average computer is dusty because the constant on and off again, feed dust and letting it settle inside where the fans cant blow it away
This explains why I don't get a lot of dust in my computers as I run them 24/7.

I JUST put 5 new static pressure optimized case fans into my case last week, so great timing with this video! I have all five fans as intake based on an older video where Linus recommended that setup to mitigate dust buildup. However, I see that there's really no "hands-off" fan configuration. I will clean my dust filters every month and take some canned air to the interior just to be safe. *EDIT* Thank you for the suggestions everyone! I've changed the rear fan to exhaust so I still have positive pressure in addition to moving hot air out actively instead of just pulling in cool air.
19thHour Unless you have a rad behind all of those case fans you have no reason to run SP fans for everything. Take some back for air flow models.
19thHour you fucked it in all possible ways. You should not use static pressure fans, and all intake fans is not a good idea.
If you wanna good ventilation you will get more dust in. Use less fans and/or good filters you will get less dust.
SP fans are designed to overcome resistance - if the case is restrictive in some way (fine meshes, air filters, grilled etc.) then they may well have been the better choice.
you can use better filters and cover all holes on your case with them but then you'll still have to clean those filters. Btw, no need to clean your case every month. Twice a year is fine unless you got your PC in seriously dusty place.
Awesome, I'll keep this in mind for my next PC build

jared varner It’s cryptocurrency. Nobody should generalise crypto as btc as they are majorly different. If you are complaining about something, at least know the facts
A couple years later, I have a new thing you could test. You tested in, out, and in between. Can you test "flow" oriented cases [like servers]? I'm referring to cases where the air is meant to come in the front, go out the back, and with no openings in between, like a wind tunnel. And since the context is servers, you could probably test high fan speeds, medium speeds, and low speeds.

I remember cleaning my very first PC after using it for 6, 7 years, what a gory sight that was.
I only cleaned it as it started to turn off due to overheating.
(Didn't know much about PCs back then)
One thing I've found is that when I go to homes where the client smokes, I find a lot more dust sticks in the computer. It's even harder to wipe off, because the smoke residue creates a slightly sticky layer on everything.
Smoker here, can confirm. Nicotine sticks to everything and makes everything sticky with a thin yellow layer of nicotine (including your white ceilings and walls, which won't be white for long). Not good.
its the tar, not the nicotine
Is tar yellow?
Confirmed, my mom is a 40 year smoker, and has wood heat. I have to go clean her PC at least once every 3 months, it's awful :( Good news she is moving and will be quitting smoking, and no more wood heat! Yay!
wait till u get a vapers pc :) its a little sticky also
I wanna see Luke more often
I suspect there's a lesson here which no one caught:
Outtie was pulling a decent amount of air from the big filter on bottom, sure, and also a bit from other areas. What this means, though, is the pressure near the intake areas was probably lower on outtie than it was on innie, and I suspect that as a result, _less total dust_ was being pulled into the case to begin with. Sure, the dust particles are light, but they're definitely heavier than air, and they're definitely not going to respond to changes in air pressure and air flow the same way that air is going to.
I suspect a further test that could add valuable data would be to repeat outtie, but leave all the filtered intakes with no fans, and cover over any unfiltered holes in the case with tape to seal it up everywhere else. I suspect that would result in the lowest amount of dust.
Something I wonder is if a fan will pull more dust through a filter than a very steady, equivalent air flow. Because although the total air flow would be the same, the fans are essentially beating air through the filter, while the bottom filter on the outtie, for example, has a much gentler and more consistent flow, with the same net movement of air. Might this make a difference?
I really appreciate this test.
That being said, you should obviously have filters on all intakes. I bet Innie would look fine with filters on everything.

I see them after a week, my house is REALLY dusty, have to clean my desk and pc filters atleast once a week. Help me.
Same mine looked like a fucking dryer filter after like one or two uses and that was less than a month.
Unless you have heavy-duty airfilters running in multiple rooms of your house, they're always going to be dust. Your skin and hair, dust brought in from outside, dust from breakdown of materials like carpet and clothing and books... there's just too much going on to keep a house free of dust unless you've go some serious filtration going on.
saniopurulent
I’m pretty sure that’s just an old wives tale.
zeemonkeyman1 No, he’s correct about skin being one of the largest components of dust. Kinda gross to think we all breathe in each others dead skin particles all the time lol.
Thanks for the inspiration! my PC shall help filter my air in my room!
Another thing this video shows is that the stock case filters are just not good enough. One reason I use those cut to fit A/C filters over all the intakes of my PC fans. More work to replace them but taking the hard work involved in cleaning a dusty and clogged PC, it is worth it.
You should also do on the floor vs slightly raised vs on a desk for dust.
Luke's a really sound guy. shame he doesn't make many videos for you guys.
WOLF Well I mean it doesn't help that he left the LTT branch of LMG.
For a super cheap option, I recommend simply buying panty hose and stretching them over your intake fans. I've had panty hose on my intake fans for the past two years and they catch a ton of dust.
It's embarrasing buying pantyhose though....
They'll also slow down airflow, which may result in insufficient cooling.
Do they attract a lot of Male fans?
Buy it from amazon.
nul, so does literally any filter, technically speaking. Have you ever seen stretched panty hose? They're basically thinner than any filter you'd buy. If you're so worried about potentially losing a degree of coolness because you're using panty hose as a filter, then maybe you're not the target audience for this lifehack. If you're super serious about your temps then you shouldn't be skimping on your cooling and airflow to begin with, and if you are only doing light overclocking at best, one layer of stretched panty hose over each intake fan is fine.
0:19 i didn't watch this for another 10 seconds and thought he actually was fired or something lol. Apparently LMG is building Floatplane, a video streaming service, with Luke leading the program, meaning that while he technically doesn't work for LMG anymore, he'll still be in the building and doing stuff there, just as a part of Floatplane instead.
Smoking & having pets in the same room as your pc is where the mad dust comes from in my personal experience of pc repair over 10+ years.
Ditto. Have a smoking friend with 2 large dogs and a cat. He played games in laptop and smoked and did that in kitchen for 3 years. After that laptop simply died due to overheated mainboard that was literally covered with tobacco tar grease mixed with dust and fur. Primary malfunction cause was GPU which popped off from mainboard. There was nothing to salvage anymore. Now he play his stuff in desktop PC located in another room on table. That build is now much cleaner with occasional dust that is easy to clean.
@@KrotowX there's little more disgusting than tobacco tar grease... especially if the inhabitants of such place don't even clean the most basic surfaces
Or in/near the kitchen.
I just have the pets (2 cats 1 dog) and I have to rinse my dust filters on my HTPC every month.
Those filters don't block enough dust. My case (NZXT Source 210) did not come with filters, but I made my own out of a cheap window air conditioner filter you can buy for a couple dollars. It is probably 3 times as thick as the ones in that case. I put filters over all the intake fans and blocked off every other hole in the case with tape, even little screw holes. After 2 months, my filters have a thick sheet of dust covering them that you can litterally peel off if you want to. The inside stays mostly clean except for some really fine powdered dust that makes it through.
They are more effective in a house
The issue with that is seriously reduced airflpw
Its a bit like mounting radiators to every hole in your case only that filters are way denser and less tall. I hope your fans are feeling fine.
But doesn't this restrict airflow? Are the components hotter with thick filters?

Some people say they don't, some people say they both count as engagement. Who knows? At this point all we know is that youtube is a big black box, a big shamelessly lying black box.
I'll like the _video._ Not your spam comment.
I was referring to the video, hehe :) I only realized it could be interpreted as an attention grabbing comment after I refreshed and it had a ton of likes. Anyway, the important part is to like Luke.
yeah nd the likes incourages the creator to make more and better content, that's the important part! That will have a positive outcome in the long run cuz people will like and subscribe and the channel will keep growing and from there their vids will probably pop up one day on new strangers and they will watch the video and like it.

3.6 roentgen. Not great, not terrible.
It looks like the In-Between case had more dust on the fans due to it moving more air through them. Since the intake fans weren't fighting against too much positive pressure inside the case, as they were with the all intake scenario, they could push more air into the case. Also, since they concentrated the intake through the filters rather than just anywhere air could get into the case, as in the all exhaust scenario, the filters appeared dirtier again due to the greater amount of air moved through the case. In all of these scenarios, the GPU and CPU temps of the In-Between setup should have been the lowest, and would just require a little more attention to cleaning the filters as they got dirty.
Exactly 👍🏼
Its finally here!

Hayo steeze!
I want someone to look at me the way Luke looks at Linus when Linus talks about FreshBooks.
1:00 video starts
Yes there is more than just the results - they talk about where the dust builds up, how cases without certain filters may act etc.
Who wins a fight? Tunnel bear or thermal grizzly?
Aviv Gannon It believe thermal grizzly because it is literally some metal
Aviv Gannon Tunnel Grizzly
BearGrizzly
No temperature readings?
Yeah, I wished they would have done thermals and benchmarks to see how the performance of the machines were altered by the dust and potential heat issues.
Stay tuned for part 2! Brought to you by TunnelBear
TunnelBear, the easy to use temperature reading soft.. ..oh wait :)
Yeah I thought this was gonna be the main thing. I don't care about the dust, I clean it anyway. I do care about temps.
If you look at the cable management video, the tiny restriction on airflow the dust provides wouldn't have made and real difference
They finally have the results!
OsDoesCOD Not the results we wanted though.
Where are temperature results.
How much of a difference was measurably between them.
Does that thin film in the balanced system make much difference to all out.
Please make more videos on this topic!!
Do a temperature test with all of the builds with the dust still in the case.
not enough in them to give a measurable difference guaranteed you can see the heatsinks were not blocked off with dust.
Santa Clause Who knows for sure? That's why they should test it. Cleaning dust out of the case's intake lowered my Pentium D's idle temps by 10°C, an it was looking like the last case in the front, but it has an airduct that pulls in from there, directly onto the CPU.
Unless it was absolutely CAKED in dust. It wouldn't be that extreme of a difference. It would only act as an minor insulator.
I live in Sydney, Australia. These are pretty much what a PC looks like after a few days in spring due to pollen and assorted plant fines. :/
@bashpr0mpt ^^^
this was my issue too (still is but i have made it a little better). If it isn’t already, place the pc higher off the ground. maybe at least 2 metres? mine is 3 metres up and it is at least twice better. hope this helps
@Spectre
Why stop at 3 meters? I hold mine right on the chandelier of my living room.
@@oldencreek6587 mine is on the roof 💪
@@user-yc6vr8vn5j how do you even reach the on/off button on your PC?
hell no, you didnt make the temps tests after all the dust, that would have be the best conclusion of what setup is best.
If your system is that dusty you shouldn't be worrying about temps, you should just clean it
Spencer Never. If my system doesn't hit 100c, it doesn't need a clean.
batemen is right ya know.
I've seen PCs with literal dead insects on the PCB, but never a single one which got shorted by dirt.
Firstly I realise it's text. But I thought it was obvious I was joking.
Secondly, I have never known even the dustiest PC to short through dust.
I've heard the tale before, but I wonder how true it is.
I guess it depends on the content, but in the countryside our dust isn't very conductive.
Literally measuring resistance with a multimeter of ground (potted plant) 5mm apart and don't get a reading in the dry. So more than 100kOhm.
I guess city car fume and such like dirt may be more conductive, but that would be an interesting test.
Use a HEPA filtered vacuum to hoover the air in a city for a day around polluted roads (not the floor.) then compare to the countryside.
An artist of all people had done this. He made a brick from the dirt in the city.
I guess you could test it's conductivity and then know if it's bull it plausible.
After all, it's 12V mostly.
I think I posted this before but your dry warehouse dust is a lot different (fine grains) compared to most people's house and specifically bedroom dust where there's carpet, bedding, towels etc, those long fibers really stick across heat sink fins and form dust bunnies etc!
Thumbnail : HOW MUCH DUST??
Me: Dust 2
Holy shit i remember watching the setup video like 2 years ago and thought one year was ages away, now here i am remembering that this was even a thing.
Time is weird
in a couple of moments you will be on a deathbed not remembering this and still thinking that life is weard
Nice
*Mamamaamamamamamamamama*
Only reason the in-between case had a noticeable amount of dust, was because one of the top fan slots was empty. Dust basically fell in.
Just watched this and I must say it's pretty logical. All out produces way less dust inside, the only problem with that is it also provides the least cooling.
That's not true. It depends on your setup, but, even then, it's pretty comparable. The difference would be a couple of degrees at best.
Dust from construction is not like typical computer dust. Typical computer dust contains things like human skin, pet dander, smoke, etc all of which are stickier than dry-wall dust. Notice how a lot of the dust is just sort of sat on top of horizontal surfaces instead of stuck all over every single surface.
This, not everyone can have a computer room.
Exactly what I was thinking, also the upper half of the internals were mostly clean as stone dust is heavy.
That's why the inny worked so well I think. The dust was naturally heavy so, coupled with the downwards air flow, it just all settled on the bottom filter without going anywhere else.
Exactly what I noticed. The dust in the computers just fell through the open top and did not came in throught the ventilatin holes.
After 1 year of bench-marking 3 systems with 3 different air pressure tests, the results are... inconclusive. This however, is not a failed experiment!. Far from it! This actually helps us to better understand that dust enters the system, no mater how you try to avoid it! What we can learn from this is, that having decent filters at ALL vents is important. Whether it's blowing in or out, filtration is key! If you place your system on the floor (which I think the majority of people do still), then the key thing to note from this is:
That we should have decent filtration at the bottom of the case, regardless of pressure placement... Gravity is the king-kong of dust problems! From what we saw, top dust seemed to have very little baring on the overall results of the 1 year negative/ positive/ natural air pressures inside the case. Despite there being a lot of construction around the environment for all 3 systems.
The bottom filter was key! It makes logical sense right?! When you think more about it: Dust particles are heavy! They don't take long to hit the ground after being air-borne. Those dust particles that miss the case completely, or those that are drawn out, or blown out of the case, EVENTUALLY end up on ...... the FLOOR (under or around the case). So the most important factor is (besides having internal flow ), to ensure you have good circulation (negative or positive), and always blow air away from the side facing the floor :)
I hope i didn't upset or undermine anyone in my resonance to this dear Watson(s)! But it seemed like clear deduction.... a process of elimination!
Go Linus Tech Tips... and thanks Luke for coming back to conclude this experiment.
well no it was a stupid test, the most common setup recommended is a positive pressure setup with more intake fans than outtake to avoid dust coming in through gaps.
But unless all the intakes are filtered that's meaningless. If you don't filter every intake fan you're wasting time in dust prevention.
Nicholas Payne-Roberts that's a lot of words
I have the same case, on the floor, and placed a extra fan on the bottom, its now in from the front and out the back and bottom, so it doesnt suck any dust in from the bottom. I will just have to see how it looks in a couple of weeks :)
What I take away is get rid of air filters for better airflow at lower RPMs and just clean your room and PC regularly.
« It depends »
Thanks for waiting
Story of every "what's better" video on this channel.
Because it all depends!
PC enthusiasts love to constantly fight over what's better with anything PC related, while at the end of the day it always depends. That's kind of the point of this video series, lmao.
LRM12o8 The custom PC world is so vast that there can’t be one single right answer
If you guys had every been in a factory setting (especially a textile mill), you'd see some serious dust-covered PC's. Where I work, if I just lay my phone on a flat surface out on the production floor, the screen would be completely covered within an hour. The computers there run 24/7-365. The one I've been using has been there at least 6 years in that environment and I have no clue when the last time they were powered down, much less cleaned.
D H hate to see what your lungs look like
@@uni4rm Well I've never smoked anything in my life and, up until recently when they were all confiscated, I wore an N95 mask any time I'm on the production floor.
I sneezed 8 times my eyes are watery and I have rashes all over my body from watching this video
I think you may be allergic to dust.
@@PunxTV123 The fuck?
Witch Doctor
You ok?
Bless you
@EffectsAE i dont remember, this was almost a year ago lmao
I found it odd that you added two more fans to the balanced system. Two systems were the same and one was different. That kind of skews your results!
Tried to balance overall airflow i think due to the resistance that the filters create. Just a guess though.
@@themightychinful Yeah but they could have had the two extra fans on all systems and still configure them all push or all pull
1:25 OMG WHO GOT THE IDEA TO MAKE A MOUSE CLOCK !
I believe Yvonne did
Keen observation @Betafridge :)
Actually it looks lit but i only have 1 mouse in my “dead pc part box”
Id also like to collect dead motherboards to put it on my wall
I'd be interested in seeing the temps over time for each system... great test guys.
A shorter temperature test, for a few hours, should be enough to compare the systems' cooling performances. IIRC Luke made a video comparing airflow setups in 2015.
Linus OS, make it happen someone.
Linus dosent like linux so it wont happen
Let me guess, it'll crash
Just drop it.
Lol sorry I dont want ad popup spam like its the mid 2000s.
Linus and Linus should make Linus OS together!
Open Case Master Race reporting in. Ironically enough, I have actually experienced less dust build up with the main/side panel off than I have with it on.
Makes sense, dust will keep moving because of the fans and it will not stay trapped inside
heyou2424 same. I don't even know where my panel is
Also in your case you got zero to none airflow with an open side panel
If you have a good fan configuration and set up the air will move faster through the case. With the side panel off you do not really have an airflow. If your fan configuration and set up is bad it will not make much difference. There are enough tests out there proving the point. If you have better cooling with the side pannel off it means that you need a better case or just improve the airflow.
I have this case, and use fans, this video is actually useful for me. Also, 1 year already? (Honestly I completely forgot about this)
More than a year.
Yeah, Fractal Design R5, really good case.
got it myself
i can confirm its good :)
I don't have a Fractal Design R5; I cannot comment on how good it is.
Great testing nice to see the differences, my passing thought was, as much air in on the front, then out on the top, bottom and rear.
Example on this case.
Air in at the front to maintain a fresh clean supply (2x fans), Out on the bottom with 1x fan near PSU that should cover the graphics card and psu, I’d also put tights over the the bottom filter where the fan isn’t installed.
The top and rear should be outs 3x fan’s, this should maintain the negative air around the cpu and ram.
