Because, as a nerd, you're supposed to be productively lazy. Outsource the air blowing to your fans. Duh. Build a RUclips channel, and have your fans come over and blow air into your case. Problem solved.
Super finds Luke! One interesting thing I've found through my own experiments is that having a *direct* flow of air to a particular component helps temperatures significantly (rather than having to go around components etc). Not something that's easily done in a normal case unfortunately though.
+DIY Perks It's also easier to get direct airflow on a GPU with a CPU tower heatsink as in your build. Out of curiousity, how much did it cost you to build a case rather than buy one?
+DIY Perks Your case is superior in design to what anyone could find out on the market. The closest thing that I could find to it was the Silverstone FT05 (or RV05). These cases have the rotated motherboard design and also have VERY good case fans that provide direct flow of air, the Silverstone Air Penetrators. But a case like this doesn't have room for a tower heatsink on gpu like yours does.
I have three fans intake, three exhaust, not counting the ones on the CPU cooler or video card. I read at least 10 emails a day, so you can never be too safe! :P
@@Zeroneii3 Um....no. The better the air moves straight through with no "kinks" the better. Try putting some smoke through so you can see the flow. I test mine several times a day....;) There's only space for 5 120s in my Neo Air case. two front, two top, one rear. But I still fit 6. I front mounted a 120 AIO with push pull fans.
This is easily one of the most useful videos. Coming from a stock Dell XPS Desktop setup, I think just adding 1 front fan would make a lot of difference.
I have the same, added the iograded heatsink and fan, i9, 3080, a noctua too fan and maybe will add a 2nd noctua. People arw crazy to expect better. Its hated on but enough for gaming and great at desktop and I added more RAM just in case haha.
+hadron89 In my Define R4 I would do intake front and bottom, so that's three fans intake. 2 140 in front (with filter) and one high pressure fan at the bottom. Now with the exhaust, I have a H80i and the fan is pulling instead of pushing air on the fins. I have two 140s at the top exhausting also. So that's three intake and three exhaust which is neutral air pressure.
@@Picklebottom12345not all 120mm. On my intake I have 2 200mm fans, and then behind it are 3 140mm fans. The 200mm look nice but considering the front is tempered glass, I do need more static pressure than the 200mms can provide. On my CPU 360mm rad, which is mounted on the side of the case, I have 6 120mm, and then my gpu rad, which is also 360mm, has 6 120mm fans as well. Then my exhaust fan is a 140mm. The other 3 are the chipset fan, (x570), the gpu vrm fan which is 92mm, and then the psu fan, which is 130mm or something weird like that.
@@dapz oh I didn't know we were counting built in fans (like psu and gpu ones). also I didn't realise there were 200mm ones. You must have a massive case right?
@@Picklebottom12345 yeah, its pretty big, and wide too.200mm fans are one of the largest fans you can commonly find in pcs, though 250mm fans have been made for pcs, just very uncommon. not including built in fans i would have 18. its about 65 decibels at full volume, i actually have a vid of it on my channel.
@@larry570 Years ago, I saw a build on a forum. They got a bar fridge, built the PC inside, drilled holes for the cables & sealed them with silicone, then put in a TON of moisture absorbers. Ran pretty cool, overclocked real well.
@@maxvisser9528 I also installed a Huey and, for good measure, I also put in a sabre engine so that I can effectively remove heat from the case and use it for heating my hot coco
Awesome video Luke! Would love another test for positive/negative setups with one, two, three fans at different locations on the case...hmmm... maybe a video idea for something i should do :p
It's amazing they didn't mention fan orientation although it IS possible to tell by watching the video, The "back" side of a fan (where visible wires run along the frame towards center) is the side air will be blowing towards, so for example at 9:28 - 9:30 when it shows the closeup of the top fan you can see the wires so it is setup as an Exhaust fan. We can of course assume the front & rear fan orientation as it wouldn't make any sense otherwise (rear = exhaust / front = intake).
Looking back at the old videos, the improvement in production quality is massive. Audio is so much more crisp, and the lighting is perfect and diffused. And that's just at first glance. Missing Luke hosted videos though lol
Very informative and well done. The one consideration that I thought you would include is the CFM of the fans. CFM airflow determines how much air is being moved into the case (intake) or removed from the case (exhaust). I would think that a balanced CFM would be the goal of cooling the compartment. You want the intake and exhaust airflow to be near the same. There are cheap devices that measure airflow. I think they are called airspeed measurers. I would also advise using fans that are speed adjustable. This would help you to balance the case airflow. It's not all that important that you agree or disagree with me as long we both agree that warm air RISES.
The pattern here seems to be that if an intake fan has a matching exhaust fan, it has a good effect on cooling, and front fans cool the gpu better (the lower the better maybe) and exhaust fans help cool the cpu better. You guys should repeat this test, but use AIO radiators of different sizes and mix and match the fans.
Hey, when i was building my pc i made a quick search on it too, front are intakes, rear are exhausts, top is for exhausts too beacause the heat rises to the top so that makes sense.
+Dmytro Lienko They tried to get metric going in the US didn't they? Americans just got too confused. Like wtf 'murica. They use "calories" instead of kilocalories. So if you try to explain to them how much joules go in a calorie they'll think you're off by a factor of 1000.
The total average delta T between the baseline configuration and the addition of more fans represents the total cooling capacity of the system. Due to the specific heat of air, it takes so many watts to raise a volume of air 1 degree C. Therefore going from the T4 CPU cooler alone to 1 front fan + 1 back fan represents adding 480W of cooling capacity. When you add the second front fan it goes up to 600W. Adding the next top fan gets you up to 720W and at that point you are removing heat way faster than your computer can produce it.
My approach to case fans (after 2 factory fitted ones included with the case failed) is. Buy a case without fans if possible, or remove if not. Buy some decent ones. Depending on how sensitive to noise and tone you are this can be quite in depth. Also pay attention to airflow (usually given in m³/h or cubic meters per hour) I'd say you want a minimum of 50m³/h for a 120 or 140 mm but higher is better, a high quality fan will get close to double this and should be much quieter. If you can live without LED's you'll often get a better quality fan (Corsair for one the AF 140 with LED's is lighter than the non LED variant) Pay attention to the bearing type, sleeve bearings are entry level, ball bearings are better. Personally I use Noctua fans. I use their Redux model for my case fans. Many cases can fit 3 X 120 mm fans in the front or 2 X 140 mm, here I would say it's marginally better to use 3 X 120 mm if this leaves no open spaces between the fans or case rather than 2 X 140 mm that leave gaps at the top and bottom. It also looks better aesthetically in my opinion. The airflow is similar for example 2x NF-P14 Redux PWM 1500 RPM move 267.4 m³/h compared to 3x NF-P12 Redux PWM 1300 RPM move 276.9 m³/h. The NF-P14 PWM 1500 is noticeably louder tho' @ 25.8 dB(A) compared to the NF-P12 PWM 1300 @ 19.8 dB(A) + 6db(A) is much louder, I believe we perceive sound as doubling for every +3db(A) These figures are obviously specific to these exact model types and other fans will vary wildly. If fan noise bothers you it is worth going into detail. Be Quiet fans are appropriately very quiet but they sacrifice RPM and by extension airflow to achieve this. Depending on how much heat your system generates these may be an excellent low noise solution but if your overclocked CPU and powerful GPU are working hard for long gaming sessions you may require more airflow. Fan placement is not as straightforward as you might think except for the obvious front to back flow. Top mounted fans while it would seem intuitive to have them exhausting hot air (I mean heat rises, right?) I was amazed to find that flipping them over and using them as intakes, I was able to knock 10°C off my VRM temps and a couple of degrees off my RAM temps without increasing any other temps. 10°C! That's a big reduction just for flipping your fans orientation. Bottom mounted fans, I would recommend some caution here, the last thing you want to do is to be sucking dust from underneath your PC and introducing it to the interior of your case. Unless you're struggling with high temps and you've no other options I would avoid bottom mounted fans unless used with filters. In general tho' unless you live in an extremely dusty environment I don't advise the use of mesh airfilters, especially if your case has a perforated panel in front of the fans. Adding that second layer of filtration absolutely kills the fans performance, far better to run without them and invest in an air duster and regularly give your case interior a blow out. The single most important factor when it comes to airflow management is the case. If you're running high performance components then the best approach is to choose a case which is designed to optimise airflow (Gamers Nexus channel has a comprehensive guide to help you choose a high airflow case) if however your PC is more modest then you can probably get away with choosing a case design purely on aesthetic grounds. Good luck with your build.
thanks for all that detail! So in matter of fan comfiguration, given that i do have a corsair 5000d, what would be the optimal fan configuration you would recommend me? (front, rear, top) THANKS!
Always enjoy going back to see how far they have come. Luke with more to say, "So, a" cuts to tunnel bear. And then the tunnel bear notes on his phone on the desk.
Actually really digging this kinda video Luke. It's relevant for the consumer and viewer instead of the 4 TitanX black benchmarks. It's interesting to watch. Easy to play around with even if the viewer is the avg John Doe fiddling with his PC and will give huge improvements over the usual craycray stuff that gives a 0.1% improvement for a loooot of work. So thumbs up on the idea for this video. Really enjoyed watching it even for a tech veteran.
I always go for a positive pressure setup with inntake in the front and sometimes 1 in the bottom of the case if there's room and a filter that covers the position I want, then I go for a 2-3 exhaust fan setup in the roof of the case and 1 in the rear. This creates a front/bottom to back/top airflow with positive pressure, 4 inntake fans (+ PSU) and 3 exhaust fans.
I think you’re seeing diminishing returns due to excess air pressure. Your 1 exhaust fan is bottlenecking your 4 intake fans. You could possibly further increase cooling possibilities by adding bottom mounted exhaust fans, turning one of the top fans around, or using an exhaust fan that’s much stronger than the intake fans
Yeah. Once again, a place where tilting the computer on the side would probably help some if it has fans bellow the MOBO or close to it not getting the turblance and convections effect vertial towers create. Titlt the whole fucking thing on the side kind of like an Xbox or something and then you work better with physics, at least for fans colder heavy air tending to cockblock the hot air...it'd seem like you'd get a little better improvment. Pluse you get a preemo monitor stand to boot.
If you look closely, he actually adds exhaust fans on the top. So with 2 front, 1 rear and 1 top, it is in fact equalized, and slightly negative with the final config.
@@Syldar well the positive pressure is better so he should have thought about doing this experiment with negative and positive pressures with all the different fan variations.
Should've put a couple spinning HDDs in there to monitor those temps under load as well. I always make sure at least one fan is blowing on my HDDs as well to protect them during those hours-long copy operations.
I kinda dislike that while the sets seem to be more professional, ltt seems to be moving towards more of a vloggy handcam direction with less concise points and more view into the background of the videos. I feel like its almost more behind the scenes than actual content.
Using three-point or five-point lighting technique in order to get professional video is good. They only thing that this video lacks is they forgot to put less light on background. My two cents.
The whole time, even before watching the video, I had one fan configuration in mind that I was curious about. But due to the design of the case, this wasn't something that you could test. I was curious if you had a top vent/exhaust/intake, would a) two fans as intake, b) two fans as exhaust, or c) one push and the other pull (perhaps swapping as well) result in better thermals? Otherwise the rest of your setup is indicative of my own. And what about lowering fan speeds with more to be quiet (obviously many more variables and hard to fully test). Awesome as usual and thanks!
I'm building my first PC struggling so much with all the cables but your video out of the others really helped me although wish you had better lighting would of made the process better.
I disagree with you, it's not that more fans is a diminishing return, it's that when you increase the internal pressure by installing more fans it will need to be balanced. You need to tune the individual fan speeds to create an optimal pressure and flow pattern. Try using a fan controller and smoke to balance the flow pattern, then use a photohelic or a manometer etc. to set your case pressure. You may need to tape off case vents (since no pc cases on the market have flow gates that I know of) to achieve a good balance. That's how to make the fans do their job and give you the biggest bang for your buck. I've worked in the Semiconductor cleanroom industry for 30+ years, I know this topic well.
One thing not mentioned...Using a variable speed (PWM) fan array: more fans @ lower RPM make less noise than fewer fans @ higher RPM. So, if noise is a concern for you, keep this in mind.
So weird to look back at these videos from around the time when I started watching LTT. Luke is in them and the content seems so unprepared and quickly put together. Also Nick doing simple tasks like getting some peripherals for the WAN show set instead of only sales is odd. Now there are people for the inventory and loads of writers to prepare everything for a video.
These are so nostalgic, tbh its sometimes refreshing to see it a bit less prepered, there is a reason (except lasiness that @TechnologyConnections does no effort november). Sidenote, tech has advanced so much in these 7 years that this production quality can perfectly be achived by 2 brothers, a phone and a decent pc
My strix 1070 idles at 33 degrees with a side intake fan and no gpu fans running. Without it is 53 degrees so it's a huge difference at idle but under load it doesn't matter much at all.
Custom Zombies idle Temps mean nothing. I've personally tested my HAF 932 and the side panel fan made very little difference on my gpu Temps but surprisingly dropped my cpu load Temps by about 3 Celsius. if you have a gpu with a good cooler like the wind force 3x case fans don't make much of a difference gpu wise.
I have been following the same formula for years: Front: 3X 120mm or 2X 140mm or 1X 200mm Rear: 1X Exhaust fan on low speed Radiator: set to exhaust air out of the case. Sometimes I have another intake in front of the PSU, but thats not always needed.
+Casual Alien I've got an Enthoo Pro as well, but I've got 1x200 intake in the front, 2x140 intake in the top, 1x140 intake in the bottom and 1x140 exhaust in the rear. The Pro has got so many holes in the back of the case that even setting all fans bar the rear one to intake like I have doesn't cause significant internal pressure...
+Casual Alien a tier 2 evga support rep told me their non reference cooler fans prefer negative pressure over positive. and since the gpu runs hotter than the cpu it would make sense to cater to its needs. following their advice and swapping 2 side cover fans from intake to exhaust i lowered gpu temp by 3c and cpu temp about the same. since before the gpu exhaust was being forced up past the cpu and through the radiator or out the back. i have 3 intake on front, 1 intake on bottom, 2 exhaust on side, 1 exhaust on rear, 2 exhaust on top rad. 2 of the front are 1 channel of my fan controller. the other front and the bottom are on another channel. the side exhausts are on a 3rd. my 2 50mm mosfet fans are on a 4th. and the 5th channel handles the 35mm 8000rpm stock mosfet fan cuz its loud as hell, i keep it at 40% always. it by itself can overpower the sound of all other fans combined at max rpm. by doing this i can force positive or negative pressure at any time by adjusting their rpm
I just moved my GPU from vertical mount with PCI extender cable back to board mount and temperature dropped from 72C to 62C. When vertically mounted it was pretty close to the glass so that's probably why. Plus the PCI extender cable adds a touch of lag to the GPU so also better board mounted.
i use an old hyper evo cooler, my top fans are one intake 1 exhaust, this creates a sort of cooling loop for the tower and makes sure that there's air flowing through my ram. After that i've got two low speed intakes in the front to keep hard disks cool and to contribute to a positive pressure environment in the case, a fan on the side to make sure my video card is getting air, an exhaust on the back to evacuate whatever the top exhaust can't. PSU is independent and all intakes are filtered. Additionally my case has some open air venting on the back which because of positive pressure are usually for excess exhaust air, and, i popped one of the 3.5" drive bay doors open and covered it with filtering foam because it's in-line with the cooling tower so that if it needs more air air its more encouraged to pull from in front than around the case. All filters do get dirty and all open vents are usually venting excess air and if I needed any more proof its working effectively, my room gets hot as hell while pc temps stay nice and cool because there is no heat accumulation within the case. I also wear headphones, so this jet engine sitting next to me cannot be heard. As far as essential fans go, you typically want 1 exhaust near mosfets, 1 intake that flows over hard drives, 1 intake that flows near video card, and, ideally, PSU at the bottom of the case. This should prevent most cases of heat related hardware failure. Case windows are not essential for a budget gaming, you have nothing to show off anyway and the objective is performance for cost so you can use the cost of a case window and spend it somewhere more important. Additionally, if you are using either a tower cooler or a liquid cooler you must make sure there is airflow on the board. There are things on a board that have no sensors but can still fail to heat, heat pockets are lethal. Even if its the cheapest most enemic fan ever, as long as it can move air over the entire board, or at least the area around the cpu+mosfets+ram, you're good.
I'd like to see comparisons between having only exhaust fans vs intake and exhaust fans. for example; 2 exhaust (back and top) only vs. 1 back exhaust and 1 front intake. Also would like to see comparison using same fan config and components in a smaller mid tower vs that giant full tower, and maybe even a mini ATX tower.

Just ordered 2 more fans because of this video. Small fan for top and back and big fans for front. Trying to create positive pressure to minimize dust all while keeping my Pc as cool as I can.
Luké Ruké lol trust me you could, i plan to use an itx board for JUST the fan headers seeing as how 1 of them can lift off okay, so if you use a lightweight itx board, 3-4 fans, and than an extension cord (for the psu) it should be fine.
Tim Beals he's actually right. It's not fair to call him a troll. Some cases have the top configured for an intake. Such is the case with my, well, case. It has a removable dust filter on the top. I can configure it as an intake or exhaust as I see fit. Though in most cases, this isn't the case. You are also correct. Most cases use the top vent as an exhaust. The whole "heat rises" thing doesn't have much of an effect in the case as per Linus. I would assume it's because the air is moving fast and in a small space that it doesn't rise much. Edit: my case also has a side vent with no dust filter. Thought my cpu cooler fan seems to be an intake rather than a exhaust. Some cases are built with a different setup in mind.
A discussion of case pressure - negative vs positive - & dust avoidance when equipping 1 or more intake fans with dust filters, might be a great topic, & it's related to this one.
I'm going to assume that it'd just because it's a lot more widely used, and PC culture is a lot more widespread than other things worldwide. That or other countries measured temps earlier than Americans
+Sunset Rider We are too lazy to change the software settings back to F'. So we have to slowly learn things, all we really know is C stands for computer temps.
Cool ^^ Hmm, making me rethink buying 2 fans to install in the front of my case rather than 1 fan. The Cooler Master Q300L case only comes with 1 pre-installed rear fan.
I have this exact case and I have been trying to figure out the best fan set up. I have two intakes at the front and 1 exhaust, but I am debating installing one more intake or exhaust
i geus that could make sense :P...bought yesterday my second fan 120 mm came home wanted to build it in, but then found out i have space only for 95 mm fan fuuuuuuck
You need to reverse the top fan at the forward section. Without any additional cool intake air, it is not logical for the temperature to drop You always need one more intake than exhaust as the pressure will push the hot air out through the crevices of the case Also, put an extra fan on the air cooler. Use only premium fans. Use a large mesh case if lower temperatures are important. Use a Ryzen 3 1200 AF ( the new 12 nm version ) I have never seen the perfect case for optimim temperatures, especially under $ 200 USD.
I went with 2 front, 1 back, 1 top. My front bottom fan made a big difference to the basement area where my mechanical drives and power supply are. Corsair 4000D Airflow case.
I know it's 7 years old, but I wanna point out the thing this video missed: *Noise levels.* He focused only on temps, which isn't the primary reason for loading up a bunch of fans. A couple of fans can run fast and blow a lot of air, but it's noisy. If you have many fans, you can run them slower to move the same amount of air, making the PC *much* quieter.
i found making them "intake" is a big NO NO, cause it sucks in all the dust that falls on top of the case, but it should be intakes for this reason alone ,water cooling, all the hot air from CPU is going up into the water cooler(if you do have a water cooler) and so the top fans should not suck in that hot air through the water cooler
I would like to see luke or linus do a video on Teraflops on GPUs and why the AMD R9 480 has 5.5 Teraflops but is still significantly slower then the Gtx1060 with only 4.4 Teraflops.
Rear or top exhaust fan alone means no cool/fresh air is being brought in, like the front fan alone does. Bringing in fresh air at pressure is better than getting hot out, as the increased pressure in the case from intake will naturally exhaust. It wont exhaust as much as having an exhaust fan of course, which is why 1 front intake and 1 exhaust (rear or top) is optimal and brings the most impact. The case also matters. This one has vents in the top, where hot air naturally goes, so the tests, 1 with rear exhaust only and 1 with front intake only, will both be affected by hot air being able to escape naturally at the top. Perhaps with a case without top vents the results between rear exhaust only and front intake only may be different, with the former having more of an impact when there's no top vents.
My first 2 cases had a fan on the side panel that would disrupt airflow. I'll never make that mistake ever again. With my current case, I took the time to learn all about airflow and diminishing returns. Settled on a *MESH* Corsair H500 and it never comes close to overheating.
I had to run mine backwards. Two 140mm intake fans on the top and one 120mm intake on the back. NH D15 with the fans pushing down towards the gfx card. Two 140mm exhaust fans on the bottom and and two 140mm exhaust fans on the front.
Deedit Noctua NH D15, it's an air cooler that keeps up with 240mm AIOs. Fitting it properly into a Corsair C70 case is what necessitated running the fans in a reversed airflow direction.
Special EDy i think i ordered too many fans alongside my Noctua d15. I'll have 2 in the front. 2 in the back, and 1 on top... And im not even Overclocking..
That setup blows hot air over the chipset, ram, and gpu if your cpu is air cooled which is why the optimal flow is front to back where the hot air has the shortest path out of the case.
Temperature would likely drop significantly. I put tape over all the random holes and vents on the front and bottom of my case, and over where the top front fan can go, so the only place any significant amount of air leaves the case is at the rear and top rear. Tested: 3 front fans only, case fans & cooler at 60% speed = CPU 65C & GPU 72C 2 front fans and 1 rear fan, case fans & cooler at 100% speed = CPU 65C & GPU 74C When removing the lower front fan for the second test, lots of cool air left the case through the lower front fan port. Also tested: 3 front fans only, all fans 100% speed = CPU 63C & GPU 70C 3 front fans/top front INTAKE/top rear exhaust/rear exhaust, all fans 100% = CPU 63C & GPU 70C 3 front fans/top front EXHAUST/top rear exhaust/rear exhaust, all fans 100% = CPU 65C & GPU 70C All tests done at 26C ambient.

@@fuge511 Yeah that should be plenty. However, if you are using the stock cooler, i would recommend upgrading to a noctua one. Also try to find a way to monitor your temperatures, and see if you get better performance with all three fans mounted at the front.
So I had a quite similar setup as used here, so I figured, what the heck, I'll just run the test myself. And surely enough, I got very similar results, with CPU temp going to 57 and GPU temp going to about 75. This seemed quite disappointing, seen how my case is covered with 200mm fans and whatnot. Then I noticed, that the most important fans, which are automatically controlled by the system to keep the noise levels down, namely the GPU fans and CPU fans, did not go to 100% during the test. So, I figured that these were probably acceptable parameters set by the system, and the automatic fan control was just trying to keep the temps to about those figures. So I manually set every single fan to 100%, and noticed a *huge* drop in GPU temperature, that now settled at around 57 degrees, while the CPU only went down to 55 degrees. So... maybe re-run the test, don't be in such a rush and ensure that the CPU and GPU fans don't bottleneck the heat transfer?
the Asus company says they get their name from PegASUS...Pegasus...shouldn't the name be pronounced like the tail end of Pegasus, not like the mexican version of Jesus?
My selfmade computer case out of wood with 3 x 140mm fans at the front, 2 x 140mm fans at the top and 1 x 140mm fan at the back cools the CPU(i5 6600k) on full load at 50°C and the GPU(R9 390) on nearly full load at 70°C
And what's with push/pull configurations? And high pressure or low pressure inside of the case? Would like to know what kind of difference that would make depending on the number of fans.
+Kazu Push/Pull configs have generally been proven to not be cost-effective. Chances are, putting that second fan on your case somewhere would have a much better cooling effect than on your CPU cooler.
I'm not talking about water cooling - I'm talking about heatsinks. If you have two fans, it is far more cost-effective to have one on the case and one on the heatsink than both on the heatsink. Same with three fans - two on the case is going to be more cost-effective than one on the case and two on the heatsink. Basically, unless you have every fan mount on your case filled, you're unlikely to get better performance out of your air cooler with push/pull.
Guys, thermodynamics basics, hot air expands, becomes less dense and thus rises. What does this mean ? Put an exhaust fan on top of the case. You should think about crashing room temperature air into components, and then circulating that air outside the case, this is exactly how thermodynamics work. To summarize, put an intake fan directly under the gpu (typically the bottom of the case), this is probably the most important one for gamers, if your cpu gets hot as well, put an intake fan towards it, typically on the side of the case. And since air expands, becomes less dense and rises, an exhaust fan on top of the case is ideal, but in the back works as well. Usually the front is for intake, not very important in this configuration. I think the ideal configuration is this, take bottom, exhaust top, intake side, exhaust back.
I don't recommend this to idiots but you can make an extra fan slot anywhere on the case, by drilling the case, you can move the PSU anywhere with the same technique, you can do whatever, it's just a piece of metal that can be drilled and manipulated, but again, I don't recommend this to idiots because if you are an idiot, you can destroy your home, and bomb iraq in the process.

Not enough, it needs to outperform a commercial airliner
+That Guy Sully Nah just install the fans ON the desk then your monitors hover too
AzBo Gaming I agree, it's very minimal. I honestly just put a fan in every spot that is made for one and it works wonders

Steps:
1. Locate all places where a fan could physically fit
2. Fill these places with Noctua
Nope I fill mine with Ezdiy rgb fans because how much of a good deal they are

Why buy fans when I can just manually blow air into the system?
Because, as a nerd, you're supposed to be productively lazy. Outsource the air blowing to your fans. Duh.
Build a RUclips channel, and have your fans come over and blow air into your case. Problem solved.
dude just fart into it. that'd neutralize the air.
You can liquid cool it with urine
Or spend $10 for a small desk fan add just have it blow into the case
Gosh... can you stop joking?!
Super finds Luke! One interesting thing I've found through my own experiments is that having a *direct* flow of air to a particular component helps temperatures significantly (rather than having to go around components etc). Not something that's easily done in a normal case unfortunately though.
+DIY Perks Well you also designed your own case to take advantaje of that ;)
+DIY Perks It's also easier to get direct airflow on a GPU with a CPU tower heatsink as in your build. Out of curiousity, how much did it cost you to build a case rather than buy one?
+DIY Perks Your case is superior in design to what anyone could find out on the market. The closest thing that I could find to it was the Silverstone FT05 (or RV05). These cases have the rotated motherboard design and also have VERY good case fans that provide direct flow of air, the Silverstone Air Penetrators. But a case like this doesn't have room for a tower heatsink on gpu like yours does.
+Daniel Schulz The whole case itself cost only £50 in materials iirc, including the wrap and paint etc.

There's only space for 5 120s in my Neo Air case. two front, two top, one rear. But I still fit 6. I front mounted a 120 AIO with push pull fans.
This is easily one of the most useful videos. Coming from a stock Dell XPS Desktop setup, I think just adding 1 front fan would make a lot of difference.
I have the same, added the iograded heatsink and fan, i9, 3080, a noctua too fan and maybe will add a 2nd noctua. People arw crazy to expect better. Its hated on but enough for gaming and great at desktop and I added more RAM just in case haha.

I agree completely.
hey i wanna ask something, if i put radiator in front panel, it's better to use push or pull fan setup? thanks b4
+hadron89 In my Define R4 I would do intake front and bottom, so that's three fans intake. 2 140 in front (with filter) and one high pressure fan at the bottom. Now with the exhaust, I have a H80i and the fan is pulling instead of pushing air on the fins. I have two 140s at the top exhausting also. So that's three intake and three exhaust which is neutral air pressure.
+hadron89 or bottom if your case allows it.

@@Picklebottom12345not all 120mm. On my intake I have 2 200mm fans, and then behind it are 3 140mm fans. The 200mm look nice but considering the front is tempered glass, I do need more static pressure than the 200mms can provide. On my CPU 360mm rad, which is mounted on the side of the case, I have 6 120mm, and then my gpu rad, which is also 360mm, has 6 120mm fans as well. Then my exhaust fan is a 140mm.

It's amazing they didn't mention fan orientation although it IS possible to tell by watching the video, The "back" side of a fan (where visible wires run along the frame towards center) is the side air will be blowing towards, so for example at 9:28 - 9:30 when it shows the closeup of the top fan you can see the wires so it is setup as an Exhaust fan. We can of course assume the front & rear fan orientation as it wouldn't make any sense otherwise (rear = exhaust / front = intake).

Very informative and well done. The one consideration that I thought you would include is the CFM of the fans. CFM airflow determines how much air is being moved into the case (intake) or removed from the case (exhaust). I would think that a balanced CFM would be the goal of cooling the compartment. You want the intake and exhaust airflow to be near the same. There are cheap devices that measure airflow. I think they are called airspeed measurers. I would also advise using fans that are speed adjustable. This would help you to balance the case airflow. It's not all that important that you agree or disagree with me as long we both agree that warm air RISES.
I have 10 fans in my system. 2 front, 2 rear, 2 top, and 4 taped onto the window.

i want to see a follow up on how positive and negative air pressure affect cooling.
It doesn't really affect cooling but more dust goes into your case if you have positive air pressure.
Edit: Edited words.
I vent from positive to negative by changing the rear to exhaust and i get less dust.
Easy Skater pardon... negative means there is more air exiting the case and positive is when there is more air entering the case

The other guy seemed pissed you were using his stuff haha
The pattern here seems to be that if an intake fan has a matching exhaust fan, it has a good effect on cooling, and front fans cool the gpu better (the lower the better maybe) and exhaust fans help cool the cpu better. You guys should repeat this test, but use AIO radiators of different sizes and mix and match the fans.
Maybe I'm stupid but a fan orientation might've made things a bit clearer.
Front fans are intake and Back fans are exhaust? How about the ones on top?
The top fans are most likely exhaust fans. Other two are just like you said.
Hey, when i was building my pc i made a quick search on it too, front are intakes, rear are exhausts, top is for exhausts too beacause the heat rises to the top so that makes sense.
Cant the top be used as intake and add fans at the bottom for exhaust (yes I know heat rises)? I know a person with a Haf X that does that.
You can do what you want. I have my front fan bringing it in, left side panel bringing it in, top fan bringing it in, and top exhausting it.

the set lighting on this is wild XD. love seeing how far LLT has come in improving quality that we dont even notice 99% of the time.
The total average delta T between the baseline configuration and the addition of more fans represents the total cooling capacity of the system. Due to the specific heat of air, it takes so many watts to raise a volume of air 1 degree C. Therefore going from the T4 CPU cooler alone to 1 front fan + 1 back fan represents adding 480W of cooling capacity. When you add the second front fan it goes up to 600W. Adding the next top fan gets you up to 720W and at that point you are removing heat way faster than your computer can produce it.

My approach to case fans (after 2 factory fitted ones included with the case failed) is. Buy a case without fans if possible, or remove if not. Buy some decent ones. Depending on how sensitive to noise and tone you are this can be quite in depth. Also pay attention to airflow (usually given in m³/h or cubic meters per hour) I'd say you want a minimum of 50m³/h for a 120 or 140 mm but higher is better, a high quality fan will get close to double this and should be much quieter. If you can live without LED's you'll often get a better quality fan (Corsair for one the AF 140 with LED's is lighter than the non LED variant) Pay attention to the bearing type, sleeve bearings are entry level, ball bearings are better. Personally I use Noctua fans. I use their Redux model for my case fans. Many cases can fit 3 X 120 mm fans in the front or 2 X 140 mm, here I would say it's marginally better to use 3 X 120 mm if this leaves no open spaces between the fans or case rather than 2 X 140 mm that leave gaps at the top and bottom. It also looks better aesthetically in my opinion. The airflow is similar for example 2x NF-P14 Redux PWM 1500 RPM move 267.4 m³/h compared to 3x NF-P12 Redux PWM 1300 RPM move 276.9 m³/h. The NF-P14 PWM 1500 is noticeably louder tho' @ 25.8 dB(A) compared to the NF-P12 PWM 1300 @ 19.8 dB(A) + 6db(A) is much louder, I believe we perceive sound as doubling for every +3db(A) These figures are obviously specific to these exact model types and other fans will vary wildly. If fan noise bothers you it is worth going into detail. Be Quiet fans are appropriately very quiet but they sacrifice RPM and by extension airflow to achieve this. Depending on how much heat your system generates these may be an excellent low noise solution but if your overclocked CPU and powerful GPU are working hard for long gaming sessions you may require more airflow. Fan placement is not as straightforward as you might think except for the obvious front to back flow. Top mounted fans while it would seem intuitive to have them exhausting hot air (I mean heat rises, right?) I was amazed to find that flipping them over and using them as intakes, I was able to knock 10°C off my VRM temps and a couple of degrees off my RAM temps without increasing any other temps. 10°C! That's a big reduction just for flipping your fans orientation. Bottom mounted fans, I would recommend some caution here, the last thing you want to do is to be sucking dust from underneath your PC and introducing it to the interior of your case. Unless you're struggling with high temps and you've no other options I would avoid bottom mounted fans unless used with filters. In general tho' unless you live in an extremely dusty environment I don't advise the use of mesh airfilters, especially if your case has a perforated panel in front of the fans. Adding that second layer of filtration absolutely kills the fans performance, far better to run without them and invest in an air duster and regularly give your case interior a blow out. The single most important factor when it comes to airflow management is the case. If you're running high performance components then the best approach is to choose a case which is designed to optimise airflow (Gamers Nexus channel has a comprehensive guide to help you choose a high airflow case) if however your PC is more modest then you can probably get away with choosing a case design purely on aesthetic grounds. Good luck with your build.
thanks for all that detail! So in matter of fan comfiguration, given that i do have a corsair 5000d, what would be the optimal fan configuration you would recommend me? (front, rear, top) THANKS!

Easy to play around with even if the viewer is the avg John Doe fiddling with his PC and will give huge improvements over the usual craycray stuff that gives a 0.1% improvement for a loooot of work. So thumbs up on the idea for this video. Really enjoyed watching it even for a tech veteran.
I always go for a positive pressure setup with inntake in the front and sometimes 1 in the bottom of the case if there's room and a filter that covers the position I want, then I go for a 2-3 exhaust fan setup in the roof of the case and 1 in the rear. This creates a front/bottom to back/top airflow with positive pressure, 4 inntake fans (+ PSU) and 3 exhaust fans.

Lothar Scholz Let's all move there. We can call our little country 'PC Land'.
I think you’re seeing diminishing returns due to excess air pressure. Your 1 exhaust fan is bottlenecking your 4 intake fans. You could possibly further increase cooling possibilities by adding bottom mounted exhaust fans, turning one of the top fans around, or using an exhaust fan that’s much stronger than the intake fans
Yeah. Once again, a place where tilting the computer on the side would probably help some if it has fans bellow the MOBO or close to it not getting the turblance and convections effect vertial towers create. Titlt the whole fucking thing on the side kind of like an Xbox or something and then you work better with physics, at least for fans colder heavy air tending to cockblock the hot air...it'd seem like you'd get a little better improvment.
Pluse you get a preemo monitor stand to boot.
@@gorkskoal9315 That's very interesting. Could you expand on the idea ? Why would a tower build work against physic, compared to tilting it ?
If you look closely, he actually adds exhaust fans on the top. So with 2 front, 1 rear and 1 top, it is in fact equalized, and slightly negative with the final config.
@@Syldar well the positive pressure is better so he should have thought about doing this experiment with negative and positive pressures with all the different fan variations.
Should've put a couple spinning HDDs in there to monitor those temps under load as well. I always make sure at least one fan is blowing on my HDDs as well to protect them during those hours-long copy operations.
I kinda dislike that while the sets seem to be more professional, ltt seems to be moving towards more of a vloggy handcam direction with less concise points and more view into the background of the videos. I feel like its almost more behind the scenes than actual content.

+Beef Ingot yeah I admit this recording was definently rushed haha. Results and content was still interesting though
Using three-point or five-point lighting technique in order to get professional video is good. They only thing that this video lacks is they forgot to put less light on background. My two cents.
The whole time, even before watching the video, I had one fan configuration in mind that I was curious about. But due to the design of the case, this wasn't something that you could test. I was curious if you had a top vent/exhaust/intake, would a) two fans as intake, b) two fans as exhaust, or c) one push and the other pull (perhaps swapping as well) result in better thermals? Otherwise the rest of your setup is indicative of my own. And what about lowering fan speeds with more to be quiet (obviously many more variables and hard to fully test). Awesome as usual and thanks!

I disagree with you, it's not that more fans is a diminishing return, it's that when you increase the internal pressure by installing more fans it will need to be balanced. You need to tune the individual fan speeds to create an optimal pressure and flow pattern. Try using a fan controller and smoke to balance the flow pattern, then use a photohelic or a manometer etc. to set your case pressure. You may need to tape off case vents (since no pc cases on the market have flow gates that I know of) to achieve a good balance. That's how to make the fans do their job and give you the biggest bang for your buck.
I've worked in the Semiconductor cleanroom industry for 30+ years, I know this topic well.

you shouldve tested a side panel fan and its effect on the gpu.
My strix 1070 idles at 33 degrees with a side intake fan and no gpu fans running.
Without it is 53 degrees so it's a huge difference at idle but under load it doesn't matter much at all.
Custom Zombies idle Temps mean nothing. I've personally tested my HAF 932 and the side panel fan made very little difference on my gpu Temps but surprisingly dropped my cpu load Temps by about 3 Celsius. if you have a gpu with a good cooler like the wind force 3x case fans don't make much of a difference gpu wise.
My 780 ti idles at 32 when ambient is 36 xD
980 idling at 38 with a Corsair H90 AIO, but at 1525mhz and 1.275V XD
yea im gonna put in a side intake fan on my rig, its an 80mm antec with blue led and 3 speeds, hope it turns out good!!
I have been following the same formula for years:
Front: 3X 120mm or 2X 140mm or 1X 200mm
Rear: 1X Exhaust fan on low speed
Radiator: set to exhaust air out of the case.
Sometimes I have another intake in front of the PSU, but thats not always needed.
+Casual Alien Found the positive pressure bro
200mm fans don't make good intakes, dual 140s are definitely the way to go if your case supports it
Kyle McHale I only mentioned the 200 because thats what my Enthoo Pro came with. When given a choice I always pick 2 or more 140 fans.
+Casual Alien I've got an Enthoo Pro as well, but I've got 1x200 intake in the front, 2x140 intake in the top, 1x140 intake in the bottom and 1x140 exhaust in the rear. The Pro has got so many holes in the back of the case that even setting all fans bar the rear one to intake like I have doesn't cause significant internal pressure...
+Casual Alien a tier 2 evga support rep told me their non reference cooler fans prefer negative pressure over positive. and since the gpu runs hotter than the cpu it would make sense to cater to its needs. following their advice and swapping 2 side cover fans from intake to exhaust i lowered gpu temp by 3c and cpu temp about the same. since before the gpu exhaust was being forced up past the cpu and through the radiator or out the back.
i have 3 intake on front, 1 intake on bottom, 2 exhaust on side, 1 exhaust on rear, 2 exhaust on top rad. 2 of the front are 1 channel of my fan controller. the other front and the bottom are on another channel. the side exhausts are on a 3rd. my 2 50mm mosfet fans are on a 4th. and the 5th channel handles the 35mm 8000rpm stock mosfet fan cuz its loud as hell, i keep it at 40% always. it by itself can overpower the sound of all other fans combined at max rpm. by doing this i can force positive or negative pressure at any time by adjusting their rpm
I just moved my GPU from vertical mount with PCI extender cable back to board mount and temperature dropped from 72C to 62C. When vertically mounted it was pretty close to the glass so that's probably why. Plus the PCI extender cable adds a touch of lag to the GPU so also better board mounted.
i use an old hyper evo cooler, my top fans are one intake 1 exhaust, this creates a sort of cooling loop for the tower and makes sure that there's air flowing through my ram. After that i've got two low speed intakes in the front to keep hard disks cool and to contribute to a positive pressure environment in the case, a fan on the side to make sure my video card is getting air, an exhaust on the back to evacuate whatever the top exhaust can't. PSU is independent and all intakes are filtered. Additionally my case has some open air venting on the back which because of positive pressure are usually for excess exhaust air, and, i popped one of the 3.5" drive bay doors open and covered it with filtering foam because it's in-line with the cooling tower so that if it needs more air air its more encouraged to pull from in front than around the case. All filters do get dirty and all open vents are usually venting excess air and if I needed any more proof its working effectively, my room gets hot as hell while pc temps stay nice and cool because there is no heat accumulation within the case. I also wear headphones, so this jet engine sitting next to me cannot be heard. As far as essential fans go, you typically want 1 exhaust near mosfets, 1 intake that flows over hard drives, 1 intake that flows near video card, and, ideally, PSU at the bottom of the case. This should prevent most cases of heat related hardware failure. Case windows are not essential for a budget gaming, you have nothing to show off anyway and the objective is performance for cost so you can use the cost of a case window and spend it somewhere more important. Additionally, if you are using either a tower cooler or a liquid cooler you must make sure there is airflow on the board. There are things on a board that have no sensors but can still fail to heat, heat pockets are lethal. Even if its the cheapest most enemic fan ever, as long as it can move air over the entire board, or at least the area around the cpu+mosfets+ram, you're good.

Luké Ruké lol trust me you could, i plan to use an itx board for JUST the fan headers seeing as how 1 of them can lift off okay, so if you use a lightweight itx board, 3-4 fans, and than an extension cord (for the psu) it should be fine.
***** for that money I can buy a new game
Alex The Zen Dragon Slayer *an overpriced game, or 2-4 steam games (but to play on a computer without sufficient cooling mind you)

Fans are blowing in or out? How do you forget to tell us that?
Marc Marc in more than out is always better
Usually, front fans are pulling fresh air in, top and rear fans are pushing hot air out. I think he did this way ;)
Why the hell is it not obvious to you? Top and front are intake and rear fans are exhaust.
The norm is rear & top are exhaust (heat rises) & front is intake... Centiliter is trying to troll you.
Tim Beals he's actually right. It's not fair to call him a troll. Some cases have the top configured for an intake. Such is the case with my, well, case. It has a removable dust filter on the top. I can configure it as an intake or exhaust as I see fit. Though in most cases, this isn't the case. You are also correct. Most cases use the top vent as an exhaust. The whole "heat rises" thing doesn't have much of an effect in the case as per Linus. I would assume it's because the air is moving fast and in a small space that it doesn't rise much.
Edit: my case also has a side vent with no dust filter. Thought my cpu cooler fan seems to be an intake rather than a exhaust. Some cases are built with a different setup in mind.
A discussion of case pressure - negative vs positive - & dust avoidance when equipping 1 or more intake fans with dust filters, might be a great topic, & it's related to this one.
Me: buys big industrial fan to cool the whole PC
My electric bill: =(
AmazedPlague659 true my electric bill are MORE expensive =(
Your electrical bill: :(

That's a bit of an overkill for a small system
Looks like I had my fans set up for the best performance the whole time. 2 in the front, one in the back and one on the top
Why are computer temps the only thing in America measured in Celsius?
I'm going to assume that it'd just because it's a lot more widely used, and PC culture is a lot more widespread than other things worldwide.
That or other countries measured temps earlier than Americans
+Sunset Rider We are too lazy to change the software settings back to F'.
So we have to slowly learn things, all we really know is C stands for computer temps.
+Sunset Rider This show is in Canada.
Because Celsius is actually used in America quite often for accurate measurement and professional measuring.
+Sunset Rider Because people actually care about getting a logical, accurate reading.
Luke's tech tips was pretty good
I love Luke’s face right before he starts talking after a transition.
im such a big "fan" of ur channel ;)
haha..
+SMURF oKING heh
nah ill stay
+SMURF oKING LMAO I loved this one m8
Nailed it! xD
Cool ^^ Hmm, making me rethink buying 2 fans to install in the front of my case rather than 1 fan. The Cooler Master Q300L case only comes with 1 pre-installed rear fan.
You can buy 4pack fans fr cooler master, its cheap
You definitely need more than the one for that case. The reviews are very critical of its airflow.
I have the same case. What did you end up going with and how did it work it out?
I have this exact case and I have been trying to figure out the best fan set up. I have two intakes at the front and 1 exhaust, but I am debating installing one more intake or exhaust
This video was so informative and usefull why the hell would you dislike it? Just makes no freaking sense...
"Gamers" who bought 5x $70 fans..
i geus that could make sense :P...bought yesterday my second fan 120 mm came home wanted to build it in, but then found out i have space only for 95 mm fan fuuuuuuck
+Dejan Kostic
noob :D
welcome to the internet
It's the internet. Makes perfect sense.
Would've been interesting if you also switched between all intake, all exhaust, and push/pull.
You need to reverse the top fan at the forward section. Without any additional cool intake air, it is not logical for the temperature to drop
You always need one more intake than exhaust as the pressure will push the hot air out through the crevices of the case
Also, put an extra fan on the air cooler.
Use only premium fans.
Use a large mesh case if lower temperatures are important.
Use a Ryzen 3 1200 AF ( the new 12 nm version )
I have never seen the perfect case for optimim temperatures, especially under $ 200 USD.
Hey can you recommend your top 2 cases plz
I went with 2 front, 1 back, 1 top. My front bottom fan made a big difference to the basement area where my mechanical drives and power supply are. Corsair 4000D Airflow case.
I know it's 7 years old, but I wanna point out the thing this video missed: *Noise levels.* He focused only on temps, which isn't the primary reason for loading up a bunch of fans. A couple of fans can run fast and blow a lot of air, but it's noisy. If you have many fans, you can run them slower to move the same amount of air, making the PC *much* quieter.
you did not test push, pull, that also makes a huge difference, pulling the heat out or blowing cool air in
I was thinking the same thing. Also he never said whether the fans on the top of the case where intake or exhaust.
i found making them "intake" is a big NO NO, cause it sucks in all the dust that falls on top of the case, but it should be intakes for this reason alone ,water cooling, all the hot air from CPU is going up into the water cooler(if you do have a water cooler) and so the top fans should not suck in that hot air through the water cooler
+drink15 uhm fans is for airflow, comes down to what airflow you get from how much fans you put in
+drink15 was not arguing wat the video was about, just trying to give advice on future videos he would make, think of all the agles
I would like to see luke or linus do a video on Teraflops on GPUs and why the AMD R9 480 has 5.5 Teraflops but is still significantly slower then the Gtx1060 with only 4.4 Teraflops.
The test would be more interesting by adding some fans to the sides! 😀
Rear or top exhaust fan alone means no cool/fresh air is being brought in, like the front fan alone does. Bringing in fresh air at pressure is better than getting hot out, as the increased pressure in the case from intake will naturally exhaust. It wont exhaust as much as having an exhaust fan of course, which is why 1 front intake and 1 exhaust (rear or top) is optimal and brings the most impact.
The case also matters. This one has vents in the top, where hot air naturally goes, so the tests, 1 with rear exhaust only and 1 with front intake only, will both be affected by hot air being able to escape naturally at the top. Perhaps with a case without top vents the results between rear exhaust only and front intake only may be different, with the former having more of an impact when there's no top vents.
needs the blower style exhaust fans, those things are amazing
Amazing tests, I always wondered about it.
er, the '2 in the front' the added second fan is blowing 90% into the PSU enclosure lol
My first 2 cases had a fan on the side panel that would disrupt airflow.
I'll never make that mistake ever again.
With my current case, I took the time to learn all about airflow and diminishing returns.
Settled on a *MESH* Corsair H500 and it never comes close to overheating.
I have a total of 8 running fans.
4 built in to the case
2 on the GPU
1 on the proccescer
1 standalone cooling system
Psu?
no one cares
@@kingj0n i do, m8
"proccescer"
Inentional or not, that made my day
I had to run mine backwards. Two 140mm intake fans on the top and one 120mm intake on the back. NH D15 with the fans pushing down towards the gfx card. Two 140mm exhaust fans on the bottom and and two 140mm exhaust fans on the front.

Special EDy Water or air cooled?
Deedit Noctua NH D15, it's an air cooler that keeps up with 240mm AIOs. Fitting it properly into a Corsair C70 case is what necessitated running the fans in a reversed airflow direction.
Special EDy i think i ordered too many fans alongside my Noctua d15. I'll have 2 in the front. 2 in the back, and 1 on top...
And im not even Overclocking..
That setup blows hot air over the chipset, ram, and gpu if your cpu is air cooled which is why the optimal flow is front to back where the hot air has the shortest path out of the case.
12:25 My friend when they don't care what I'm saying
I have 2 in front + 1 in rear. I wanted to put 2 more on the top of the case, but your video made me save money (and noise). Thanks.
that dude at the end of the clip seemed really passive aggressive
For me intakes: three in the front, one on the bottom, exhausts: one in the back, and 3 up top.
Curious to see what 3 in the front and one in the back would do.
Temperature would likely drop significantly.
I put tape over all the random holes and vents on the front and bottom of my case, and over where the top front fan can go, so the only place any significant amount of air leaves the case is at the rear and top rear.
Tested:
3 front fans only, case fans & cooler at 60% speed = CPU 65C & GPU 72C
2 front fans and 1 rear fan, case fans & cooler at 100% speed = CPU 65C & GPU 74C
When removing the lower front fan for the second test, lots of cool air left the case through the lower front fan port.
Also tested:
3 front fans only, all fans 100% speed = CPU 63C & GPU 70C
3 front fans/top front INTAKE/top rear exhaust/rear exhaust, all fans 100% = CPU 63C & GPU 70C
3 front fans/top front EXHAUST/top rear exhaust/rear exhaust, all fans 100% = CPU 65C & GPU 70C

@@billowytrots8366 A for effort
You just described my case.
@@billowytrots8366 I have 5600x and 3070, when I play cyberpunk am I good with just 3 fans? 2 intake front and one exhaust in the upper back?
@@fuge511 Yeah that should be plenty. However, if you are using the stock cooler, i would recommend upgrading to a noctua one. Also try to find a way to monitor your temperatures, and see if you get better performance with all three fans mounted at the front.
I placed Noctua fans in every spot possible. All 9 of them, they work great :)
So I had a quite similar setup as used here, so I figured, what the heck, I'll just run the test myself. And surely enough, I got very similar results, with CPU temp going to 57 and GPU temp going to about 75. This seemed quite disappointing, seen how my case is covered with 200mm fans and whatnot. Then I noticed, that the most important fans, which are automatically controlled by the system to keep the noise levels down, namely the GPU fans and CPU fans, did not go to 100% during the test.
So, I figured that these were probably acceptable parameters set by the system, and the automatic fan control was just trying to keep the temps to about those figures. So I manually set every single fan to 100%, and noticed a *huge* drop in GPU temperature, that now settled at around 57 degrees, while the CPU only went down to 55 degrees.
So... maybe re-run the test, don't be in such a rush and ensure that the CPU and GPU fans don't bottleneck the heat transfer?
Fan air flow directions?
He wanted to do a realistic test, and having the CPU and GPU fans at 100% isn't something that anyone would do all regularly
the Asus company says they get their name from PegASUS...Pegasus...shouldn't the name be pronounced like the tail end of Pegasus, not like the mexican version of Jesus?
Thanks for the tip. When I heard him I was wondering if I've been saying it wrong my whole life.
Some ppl say it Ayy Zeus while others say asus as in pegasus so idk
No difference whatsoever. It’s English, however he pronounces it it’s wrong.
I've always said it as "Eh-sis". But that's just me.. and because i want to watch the world burn. 🤷♂️
The german pronounciation for example would be exactly like in "pegasus". i've said it right my whole life :D
11:50 is all you want
Thank you for making and posting this video. It's helped me understand the cooling requirements for a build I'd like to undertake. Thank you again.
My selfmade computer case out of wood with 3 x 140mm fans at the front, 2 x 140mm fans at the top and 1 x 140mm fan at the back cools the CPU(i5 6600k) on full load at 50°C and the GPU(R9 390) on nearly full load at 70°C
And what's with push/pull configurations? And high pressure or low pressure inside of the case? Would like to know what kind of difference that would make depending on the number of fans.
+Kazu Push/Pull configs have generally been proven to not be cost-effective. Chances are, putting that second fan on your case somewhere would have a much better cooling effect than on your CPU cooler.
+jedidethfreak If you're talking about radiators, then yeah push/pull doesn't really do anything. But push is better than pull
I'm not talking about water cooling - I'm talking about heatsinks.
If you have two fans, it is far more cost-effective to have one on the case and one on the heatsink than both on the heatsink. Same with three fans - two on the case is going to be more cost-effective than one on the case and two on the heatsink. Basically, unless you have every fan mount on your case filled, you're unlikely to get better performance out of your air cooler with push/pull.
jedidethfreak A radiator is a heatsink
Berenger Christy We're talking about aircooling.
Did you not watch the video?
Guys, thermodynamics basics, hot air expands, becomes less dense and thus rises. What does this mean ? Put an exhaust fan on top of the case.
You should think about crashing room temperature air into components, and then circulating that air outside the case, this is exactly how thermodynamics work.
To summarize, put an intake fan directly under the gpu (typically the bottom of the case), this is probably the most important one for gamers, if your cpu gets hot as well, put an intake fan towards it, typically on the side of the case. And since air expands, becomes less dense and rises, an exhaust fan on top of the case is ideal, but in the back works as well. Usually the front is for intake, not very important in this configuration.
I think the ideal configuration is this, take bottom, exhaust top, intake side, exhaust back.
Silver Mirai wait, something i dont get, how could we place a bottom fan? thats where the PSU is??
I don't recommend this to idiots but you can make an extra fan slot anywhere on the case, by drilling the case, you can move the PSU anywhere with the same technique, you can do whatever, it's just a piece of metal that can be drilled and manipulated, but again, I don't recommend this to idiots because if you are an idiot, you can destroy your home, and bomb iraq in the process.
