I think that even though most of these videos' results saying "it doesn't really matter", that doesn't mean they are pointless. It shows that most things that a lot of people throwing around as "essential" are more PC myths save for special scenarios... So thank you Luke and LTT
That's exactly how I view all of the Workshop videos, and I feel like that's how it'll continue to be. Although that's not necessarily a bad thing.
Thank you!!
i agree. it is nice to not stress about these little things when building my pc. Some times the little things are the things that have no solid answer. i prefer down so my psu doesn't suck in the hit air from the 2nd gpu but never tried to change it up to help flow more air out of the gpu.
that special situation where you have multiple blankets, boxes and a Snoopy doll in your case
Everyone who keeps calling this "filler content" or saying LTT has "run out of ideas" probably doesn't seem to understand what "content" actually is...
These ARE content ideas, and much more original ones than reviewing every product under the sun or making the same iPhone rumor videos as everyone else.
i am new to pc building. this helps
Preach man. 5 years later, I googled for this to get this exact piece of information. Can be so helpful!
@@Tomogeny Indeed! Even had computers for 25 years now and still going through some information to get updated and just check because i want to.
I come to his channel to get educated
10sec in to the video prediction: It doesn't matter! Just throw your hardware in a pile, squirt some thermal paste on it and finish with one or two fans. MAXIMUM PERFORMANCE
aaaand yep, difference is minuscule
10 secs? i didn't even need to press play.
+Terry's Tech how does not having thermal paste look "badass" because you can't see the thermal paste
Went right over your head, ay m8?
Loooool!!!
Next on the workshop, does case color REALLY affect clock speed?
add flame stickers for extra 200 mhz
obviously Red case color makes the fan go faster
Red Wunz go Fasta
you give it some cool stickers a name is something really cool it can improve a lot. lol
YES. because at night it´s darker than outside ;)
I love how you're not afraid of negative results with these. I know it probably gets tedious to get the same result every time, but they're very interesting to me as a hardware enthusiast slash engineer.
Whatever the results, knowing is way better than keeping our old misconceptions!
It's illegal to discriminate based on PSU orientation.
noice!
+Akil Jacob *click* Noice
*slurp* *SMUCK* noice
That sounds like filthy fan up talk to me
look at all these fan-ist bigots
I predict the result, as most of these " workshop" videos go, it doesnt fucking matter
It actually does - LTT are simple incompetent
>simple incompetent
kek
At least they aren't simply incompetent. That would be bad. I'm not sure what a simple incompetent is.
+Svetoslav Tsanev kek go on. Tell us what they did wrong in this video
Unfortunately there are way more people with little to no idea about how a PC works, and they fill the heads of other noobs with shit, so for them this is helpful.
For you it's just a vid for views for cash. (me too, where did all the interesting content go?)
Absolutely love this series, because 90% of the time, nothing matters.
I was hoping to see a comparison between top mounted vs bottom mounted power supply
Only old cases have top mounted power supply's
no. the new coming In Win Case have a top mounted or so ^^
Not true at all, There have been a few cases last year that had top mounted.
95% of cases have bottom mounted PSUs. It's extremely niche.
Still, it's pretty rare
Fucking G Fuel, REALLY?! WOOOOW MAN Use that code KEEEEEM! ROFL, what the fuck man, them ads.
nice memes, Well meme'd my friend.
shovel it down you fat pig
GFUEL. Fuel for the original gangstas? I'll stick with Red Bull, coffee, and tea. On paper it does look like a decent product but it's just easier to drink coffee.
Alex is a stupid nugget
Gfuel has been around for much longer then KhemoTherapy star.
This was was actually very interesting to me as I've personally changed from having the PSU oriented fan down, to having it fan up. I have a Corsair 550D case (without an isolated PSU compartment) together with a Corsair HX750 PSU (semi-passively cooled). While under load there is no difference in behaviour between the two setups, in idle or during low-stress tasks my PSU would reach it's thermal threshold and activate the fan every 15 minutes or so while oriented fan down. This is not the case when I orient the PSU fan up, and I came to the conclusion that the chassi fans help ever so slightly to push air through the PSU, keeping the PSU temperature under threshold. Glad to see my theory was somewhat in-line with your conclusion. While you say there is no big difference in setups, there could actually be a somewhat "big" difference during light use of the machine, as evidenced in my case. Additionally, my particular PSU doesn't have variable fan speed. If it's activated, it's loud. I resolved a big source of annoyance simply by changing the PSU orientation in my particular case.
Can i use G-fuel for my AIO coolant?
You *can*, but *should* you?
Plamen Yordanov Maybe and maybe not
why the hell not!
You should.
I believe there will be a result for the workshop videos
this video tried so hard and got so far, but in the end it didn't even matter...
Next up in the workshop-
Does rgb led strips affect temperature?
That would be yes. LED's convert around 75% of their used energy to heat. So 100W strip inside the case would be like 75W heater inside it. Very similar to adding another GPU. Tho 1W strip won't make any notable difference.
+ShadowManceri >>.
But you also have to consider in your calculations that blue leds make you system actually cooler, red leds make it way faster and green leds more efficient. So in the end it is worth it! And if you use white leds you get a little bit from everything.
+Tobias L. use christmas lights and you are ready for everything
Haha, my comment on the last Workshop drew a very similar comparison.
next up: how does north/southbridge temperature / clock speeds affect CPU overclocks
In my system it does, because the mainboard (very cheap model) throttles its clock speed if it's too hot.
don't forget the vrm!
Workshop: Proving that things we thought would make at least a minimal difference, do not do so at all. Keep it up Luke :)
What's next, "does sexual orientation affect your gaming performance?"
It does, it would just be unethical to test...
I'm sure linus and luke have an above average performance at co-op games if you know what i mean ( ͡° ͜ʖ ͡°)
it's other way around, your gaming performance affects your sexual orientation.
+failing@commenting tru
I chuckled.
I know a lot of you think this is boring, but I love this systematic testing method so I can see exactly how they did it! :D Love the workshop!
Luke I would love to see you benchmark a normal system then remove the case entirely, build like a frame to hold the components in the same place so there all floating in the air and see if the case actually helped to keep it cool with air flow
Wowa. Did not expect to see my fav siege RUclipsr here
Without a case, parts can dissipate heat easily to the atmosphere so it will mostly be better.
But isn't the case there for keeping things in place and mostly protection from water etc?
I love 1:40 where Luke just sees himself in the reflections and runs out of the picture XD
I like these videos, but I _LOVE_ reading comments from angry rage-monsters who, instead of just skipping the videos, instead opt to watch and complain about them _every time_. Poor saps. Makes my life seem platinum in comparison.
94 degrees celsius? Woah. What the fuck. Is there an invisible fire in your graphics card?
ASUS Strix ... lets slap our GTX 780 cooler on R9 390/390x/290x/290 because we are lazy as fuck to adjust it correctly and they are almost the same except they are not.
strix card (asus probably makes on the worst coolers for the 390) + stock fan curve
Well, the fans of the GPU were pinned to 45% of max rpm while running a skybox test. So what would you expect?
fan is pinned at 45%....
45% isn't pinned
What's up with the background music?
+chbrules didn't ask what song it was, but what was up with the choice of song.
Thanks anyway.
That question makes absolutely no sense.
john papple It is actually a valid question.
It's a slang and you can find the definition in the urban dictionary.
Infact, let me just tell you the definition.
"What's up with that"
A phrase used to ask about something odd, or what the point of something is. The word "that" can also be replaced with whatever noun the person is asking about. It is also common to inerject the word "fuck" into the phrase to express shock or discust.
www.urbandictionary.com/define.php?term=what%27s%20up%20with%20that
It's so damn loud and obnoxious
+Internet Enzyme like in every video they produved recently
One thing to consider: if you place the PSU with the fan UP it will create negative pressure in the case. If you have too much positive, that may be a good thing, but if you are already leaning towards negative pressure then you might be better keeping the PSU with the fan down. Another thing to consider is if you have a filter below that fan. If not then orienting it with the fan up will provide fresh air (if positive pressure in the case and all the intake fans have filters on them). I find this important since not many people are ready to open the PSU to clean it.
I love the music, sounds like an Aperture Science video
It is Mozart's Eine Kleine Nichtmusik
*Nachtmusik
"Nachtmusik" means "night music" while "Nichtmusik" means "non-music."
When the new generation take over and recognize THE GENIUS AND MUSICAL BEHEMOTH THAT IS MOZART, through games like portal because his music "sounds" like the music from those games, and not the other way around.
*Nachtmusik
I did not even notice the spelling error.
A little bit of non-music
1:42 reflection is hilarious!
The content was good, and I'm glad you're down to test things most others just take for granted, but... Man, that video quality was not up to the LTT-standard =/
I agree. Right at the beginning it was shaking a lot
Luke, when the fan ran at 0 rpm and 41c in the last test, it means that the power supply is stressed less. it would be running cooler if it weren't for the silent fan feature.
Nothing ever matters in the Workshop.
+/- air pressure is a consideration here. Flipping the PS upside down could make a difference in the overall air pressure in the case. In general you always want to maintain positive air pressure to ensure intake is only through your air filters. Otherwise have fun dusting out your case on a more regular basis!
i must admit, its kind of boring watching a video for 10 minutes only to find out "it makes virtually no difference"
Regardless of the results are boring or not, knowing is better than keeping old misconceptions. Yay science!
He said it makes him mad too that none of this is producing any tangible results.
chbrules It's still a result. Now people (at least the intelligent among the viewers) will know.
It actually does make a difference, but only in the PSU's temperature. Installing it with the fan facing downwards makes its temperature lower (on the last test it was higher because the fan wasn't even spinning to reduce noise). So the conclusion is that the fan should be facing down.
PS: However, they missed the opportunity to test something that would probably make a difference in the CPU/GPU temps: PSU fan facing up or down with no other fans in the case whatsoever.
With a basement vent and filter on your case/tower, mount the PSU so its fan is downward. As 3c to 4c can make a difference while sitting in the room on a hot day as your desktop runs. Just like your monitor, the closer you are next to it you feel the heat. Electronic components don't like Hot or Cold environments but as I learned in the U.S. Navy as a 26 year career veteran as an Aviation Electronics Technician that cooler temperatures is best. Since electronic components heat up, the ambient temperature of the surrounding area in which they operate in is better in the cold. Solder joints and corrosion plus all the stress the equipment takes being mounted in an aircraft is shattering. Like your car has struts and shock absorbers all that electronic stuff that is installed will one day malfunction, so don't live by the ocean, don't live in the dessert, don't live where in winter time the roads are salted, don't let your stuff freeze, don't drive your car through high water as if it were a submarine, and avoid as many pot holes as you can. Now take your cellular phone and toss it against the wall and on the ground and jump on it. Better yet, juice yourself up with static electricity like the Adam's Family - Uncle Fester and see if you can light up a light bulb. Remember that electricity and water don't mix. Keep you liquids a safe distance from your computer. Oh! LINUS "LTT" has several cats "pets" which he should not let near or walk all over his keyboard, top of the laptop or desktop.… they are animals and unfortunately they might pee on your (Linus'es) expensive stuff. Oh man, this was working last night … what happen to it?
@Luke There's an issue with your testing methodology;
The GPU used in the "no" basement version is a blower as I'm sure your aware, Blows and exhausts air from the case, clearly evident in the fact that the case is alot cooler in general.
Therefore, Hot air isn't being exhausted into the case, or worst yet directly into the PSU.
The GPU used in the first test does exhaust some of its air since it has lengthwise fins, but still exhausts a large amount of it into the case instead of exhausting it out.
Retry this test with a little more worse case scenario's and maintaining the same GPU's. Most GPU's do not have lengthwise cooling fins like the Asus does, so in most cases say SLI Gigabyte 980ti's or something like that, which exhaust almost all their air into the case, or many ACX coolers on 290's 290x's etc.
So if someone tries to do PSU up config, and has 2 heavy power using cards, they will find their PSU getting pretty freaking hot in a Mid tower case.
My experience of this myself is having 2x 5870's and a 8800GT all doing folding at home overnight, in a HAF932 (Bottom PSU facing UP) Having my Corsair hx850 basically burn me when I touched the side, was easily 70c+ The Single slot 8800gt was the main culprit as the two 5870's were blowers, but the 8800GT doesn't exhaust at all, and was feeding air Straight into the PSU.
This is a case where PSU up literally could have killed the PSU.
Even though the results just show that every episode of "The Workshop" is pointless, I thoroughly enjoy them. Every episode is interesting and fun to watch. It's nice to know what nitpicky things really don't matter.
I can tell the end without watching the video
"IT MAKES NO DIFFERENCE! "
Why u no undrstnd linus/luke?
It's for the viewers mainly
Because some people still can't work it out themselves.
You probably never tried something did you. Because if you did, you possibly would've run into a "Oh I really didn't expect that" moment. If you don't try it, you don't know. Period.
+Tim Derks I tried it... When I got a second GPU recently I flipped my PSU around to see if it would be quieter. It helped a bit :)
+Tim Derks I tried it... When I got a second GPU recently I flipped my PSU around to see if it would be quieter. It helped a bit :)
As an owner of a semi-passive X-Series, this is easy: Mount at the bottom of the case with the fan pointing up so it gets half-decent airflow while in passive mode.
TL;DW
PSU up with no basement.
PSU down with basement.
thanks for saving 11 minutes of my life
fizzle mygrizzle No prob.
By basement you mean that thing thats like a roof in his case? That blocked the power supplies fan when he pointed it up because it was kind of like a basement?
Actually...
PSU up if you have negative air pressure, back of case directly next to a wall, or is on the ground.
PSU down in all other situations.
If the PC case only has bottom PSU intake then you'll have to make sure to avoid all of the scenarios that is for PSU up.
luketechtips
I like luke :/
Luke getting fat, so sad.
MOVE YOUR FATASS FUCKING SLOTH !
+Alicorn Studio actually no, if you check their channel channelsuperfun they play awesome activities and games which sometimes uses a lot a of energy to play(take note that they do this every week or so)
I love the workshop. It usually gives me the go-ahead to prioritize aesthetics over anything else :)
Why is the camera shaking so much? Anybody see it in the intro?
Dennis drank a double-shot espresso instead of GFuel and got jittery af
Dennis is cracking one out over Luke I reckon.
You know why? Linus took advice from Michael Bay because he thought his videos were boring. Michael Bay then taught the camera man the art of "SHAKEY CAM".
Looks like the camera is being run handheld for some reason.
That's the results when u drink to much G Fuel, your hand's starts shaking. I recommend Mountain Dew btw
Also depends whether or not the psu has fanless mode. Obviously you want to point the fan upwards if thats the case, so heat can escape into the case.
Am I the only one that likes The Workshop??
I usually don't like videos on youtube, it's an added step to my content consumption...I don't leave comments usually either, but you guys get a like because I watch these videos all the time and I appreciate you taking your time to test all this.
when is the gtx 1070 review coming
the 1070 realese is 10th june so i guess around 5th
no gtx 1070 is comin out on 10th of june thats what was said at the nvidia press conference when they both got announced
It comes out on the tenth of june but they get/should be getting early review copies.
For the PSU upside down config where it takes in air from the case instead of under, the fan does not turn-on or is slow for high-quality PSUs.
If you add another 140mm fan, or mod your PSU so the fan is always on or taking power from the mobo, you essentially get another exhaust. Balance that with an intake fan and you get better results.
Next up: ''Does The Workshop actually give a solid answer?''
I think it's simple. Having the cooler upwards, means pulling warm air into the psu. Probably the temperature inside the case decreases, but the PSU cooler is not for cooling the inside of the pc. It needs fresh air and it can get fresh air only from the downside. That's why mostly every case has an opening for the psu cooler at the bottom. Now tell me I'm wrong?
If you have computer on carpet point the psu fan upwards.
Or if you are lazy and do not want to clean another filter..
Please point it upward people
Yeah, I was disappointed that there wasn't a shaggy carpet test.
UnleashTehNoob yes I have that but I support my case on some nice cherry wood blocks of wood, left over from my center console
these workshop episodes are ending debates all over the web. i am glad someone does these test
Couldn't you have also tested this in a mITX case, where it might've mattered?
Especially a case like the Fractal Nano S where there is very little room between the PSU and graphics card.
I also wonder if a SFX PSU (which would allow more room to the GPU) would give better GPU thermals in that case.
Does Power Supply Orientation Matter? - The Workshop Ep 6.5b
I think it's safe to say that you should never orient the PSU fan pointing up at the graphics card in that case, even if it is blower style... Most likely the same results as if it was pointed up at the basement roof like the Coolermaster case.
And most mITX cases have PSU vents... Don't know any that don't. I have a Silverstone RVZ02 with an SFX PSU and it's totally fine. And since those cases are so specialized, they aren't as modifiable as regular mid towers.
Matt Sibilleau
My point is that it's a much more relevant question in a small form factor case, since there's much less air inside them (thus having less air for the GPU and CPU to breathe), and therefore it might make a difference there, but we'll never know, since LMG don't seem to ever be thorough in their experiments.
Another thing to note is that the Corsair PSU he is using has its own variable speed fan controller. It was set to auto, had it been set at a fixed speed, not one based on temps, the case might, MIGHT, have seen lower temps.
Still a great video, love LTT
gfuel, you need that overpriced protien powder for gaming.
you think you need protien for sports? *LIES*
I drink 911 liters of gfuel a day to keep my maus clicking finger pumped as fuck
all you need is red bull or any similar horsepiss every 6hr
But it isn't even protein powder...
Caffeine , water and sugar I assume is all it is like most of them. Caffeine like any drug just makes you dependent so you can't live without it, but you never needed it to begin with, withdrawal makes you tired and keep taking it
Humans get energy from sugar so sugarfree energy drink is stupid. It's like fueling your diesel truck with dieselfree fuel! Proably just water. It's stupid.
+cpypcy The best energy drink is a fruit smoothie with oats and natural yoghurt thrown in with some ice.
Just a funny fact to point out, I have a hybrid fan in PSU as well and when I have it pointing up, the temperature in PSU is low but when fan turns on, it spins longer since it's pushing hot air downwards and as we all know heat goes up. When fan in PSU is pointing down it turns on more frequently but it runs for less than 2 seconds, since it takes fresh air from outside. And yes, I can confirm that IT DOES NOT AFFECT temperatures in the case AT ALL. :) I hoped for more tests here, like case with the PSU on top above the cpu.
Ah... the weekly pointless luke video.
true
lolz. i guess we could call it that.
The fact that the result was "it doesn't really matter" doesn't mean that the test and video were pointless. Now we KNOW that it doesn't matter, as opposed to just guessing about it.
The pointless comment?
far from pointless, everyone assumed the earth was flat too. if we didnt try to oppose that idea then we would still think that. now we know for sure that it doesnt really matter.
I personally rotate mine depending on what surface my PC is sitting on. If it's on carpet, I have it facing upwards inside the case so that dust doesn't get dragged into the system. If it's on a wooden floor then I'd have it facing down for optimal cooling. In case some didn't know, a PC that's sitting on carpet drags a hell of a lot more dust into it than those on wood.
Oh no, I can't believe LTT would actually associate themselves with a company that supports Keemstar
Oh, no...
rlly?
They probably didn't know. They're not omniscient.
Energy Core I don't know about that, LTT always seams to know who they sponsor and why, but yes it is a possibility
Aron Örn I didnt watch the video, may you explain what they did?
what really helps with temps when using internally exhausted gpus is to remove all the pci slot covers and put a fan there for exhaust. if you have a front intake fan at the bottom and the one in the back with a large gpu blocking off most of the upper case it creates a sort of wind tunnel to suck the hot air out the pci slots.
Do a test to see if all these different things you've tested combined make a difference
Knowing that it makes no difference is equally useful as any other result. Useful video.
#fillercontent
Hey guys it's luke today we are going to see if what kind of power button affects how fast it boots into Windows.
Next vid
Hey guys it's luke and today we are going to pout Mercury on a power supply and see how much it cools it
it's no filler if you put a few hours into it
It amazes me, they have higher quality equipment in this video from over 4 years ago than I do in 2019!
Good video, but ffs, cut out the music!
Very nice! But please read temps in both Celsius and Fahrenheit; just a simple button press on the digital thermometer helps those of us unlucky enough to be socialized with inferior measurement units.
lol @1:41
6:54 The fan on the graphics card is indeed pointing downwards. Great job Luke!
Does anyone actually drink g-fuel here
Hell no
I only drink tunnelbear.
i drink my piss
+bilalha123 I've been eating SquareSpace meals twice a day to loss weight
If your psu has a 0 noise mode wich turns the fans of having the fan face up is more silent because that way the heat can go into the case while if the psu fan was on the bottom the heat would have newhere to go because heat goes up. So basicly up is more silent and down is cooler case temps.
Just a theory^^
I wonder how many hours they've clocked in Crysis 3.
People sure like to complain. I really like these Workshop segments that tackle one PC variable at a time. This is actual useful information. We all love seeing the ridiculous things LTT puts together like a $30k rig that 8 people can play on at that same time, but these Workshop videos are actually useful to the average PC user.
*Luke's it makes no difference tips*
Love this series
Ah, AMD. Old reliable. You can always count on her to heat things up.
Blame Asus not AMD. It's getting hot because the cooler was built for Nvidia and slapped half-assedly onto a 390x. The fans also don't kick on until something ridiculous like 70c i think.
they did it for the 290x as well, slapping the 780 cooler on it i2.wp.com/www.ocdrift.com/wp-content/uploads/2014/03/ROG-Matrix-R9-290X-Platinum-Heatsink.jpg
To be honest. ASUS Strix is the worst aftermarket cooler for R9 290/290x/390/390x .. other OEMs run these cards MUCH MUCH more cooler in the low 80*C when in very heavy load and usualy in high 70*C when gaming.
I find it hard to believe that a DCu3 cooler would perform so poorly. The 390x might have higher TDP than a 980 or the like, but it should remain managable, I think, especially by a 3fan Strix cooler.
Something's fishy for sure
If the fan kick-in is that high, that's ridiculous, but it doesn't explain the 94c load temps.
This video still applies today and I appreciate it! Would love to see the upcoming labs content revisit this
Sorry, I only use CODE KEEM for GFUEL :P .
KEEM = 10% off vs LINUS = 40% off. Yep totally agree you should use code KEEM. ;)
+Keep it Secret gotta support the memestar
David Zeitsch Go for it, I'm sure both he and Gfuel will enjoy your money.
SUPPORT THE KN0ME
+Keep it Secret it's called a joke. Keemstar is fucking aids and i dont even buy shit from gfuel.
You need to lower your exhaust fan and increase its speed when you have an open GPU cooler (the non-blower types that leave the warm air in your case). If your case has adjustable fan slides, lower your exhaust fan as low as it can go and make sure it spins a few hundred RPM faster than the intakes. Your GPU will run noticeably cooler. You can make your system quieter overall by increasing the exhaust fan speed alone.
For the next episode, you could test if the color of watercooling liquid and tubes matters. (like transparent tubes with black liquid, white tubes versus blacks etc...).
I don't know why many people hate this series , IT IS PRETTY COOL BRUH!!
In my case having the PSU fan facing up reduces the PSU temperature a lot, average temp being 27C while the fan facing down the average is 40C... Note that the PSU fan almost never spins, i think it kicks in after 50C.
My system has the following components:
Corsair HX750i PSU, Phanteks ENTHOO PRO M Case and Asus Strix GTX 1070 OC GPU...
Oh yes and the computer is not on carpet...
that moment you realize you are in the reflection of the shot at 1:42, LOL!
8:50 lol no! PSU Fan was not spinning. The control loop of the Fan is not so sophisticated that it's a static system. It's probably a oscillating system. You just happened to measure it at the point where heat was accumulating without the fan spinning. It would probably heat up to a certain threshold where the fan would kick in to cool it down before it reaches a low threshold and the fan turns off. Basically this experiment did not capture the whole picture regarding the subject we looked at: PSU orientation. Though I think the info we did pull out points to PSU fan pointing down is always better.
What you really should consider is whether you need to avoid getting excess dust in your PSU, especially where your case is on a surface like carpet.
I really like these videos. It lays to rest a lot of myths and debates. Not to mention that Luke is really good on camera.
First thing i thought when i saw Gfuel was " LEETS GET ROOOOOOOOOITGH INTO THE NEEEWWWSS"
3 years later here is another reason to mount the psu upside as an exhaust:
if you have an AMD X570 mobo, it has a chipset fan wich sits directly
under the gpu. so its sucking in hot air from the gpu. to avoid that you
can mount the gpu vertically in some cases. and the gpu's hot air is
dumped into the psu shroud. now mounting the psu upside will suck the
gpu heat through the psu out of the case, while the upper-rear exhaust
fan takes care of the gpu from the upper side as well as of the cpu's
heat.
You should turn off all thermal throttling and fac controls when doing this. These systems are designed to keep the stuff at a fairly constant temp. As the temp inside rises, the fan spins faster with the outcome being a temp delta of close to zero.
So turn all of this off and lock in the active cooling and then run the tests. This would be a true test of the configs since it would rule out all the variables other than the ones you are testing for.
I would have been happy to see you test the difference between cases with the PSU at the top vs bottom of the case.
Yuno has 2 books because the wind one is actually the elf’s. Yuno is from the Spade kingdom so he has a book from his native land, which is that second one.
Reasons to have the fan side down:
PSU doesn't get caked with dust from the inside of the system as there's no fan filter when it's facing up while there is one while it faces down
The 24-pin is closer the the cable management holes on your chassis with the fan-side down.
Lower PSU temperatures lead to longer longevity of PSUs not quite as good as the super high-quality Corsair RMi.
corsair 760 psu facing down, lasted 7 months. RMA'd, flipped it over, runs cooler due to positive case pressure, negating the 'only spins when it's hot enough' fan. so far, much more stable.
The Temperature was only lower when facing up without basement and rear exhaust card because the fan turned at all and the when the PSU faced downward it didn't
i like the workshop because you answer questions that all begginer ask, like thermal paste aplication and psu orientation and fan setup. Realy those video are great keep going ;)
Kudos to Luke for listening to those of us who moaned about no fan speed info in earlier episodes. You can't do these comparisons, without mentioning that aspect.
The conclusion surprised me a little. I did expect a minor difference in in-case and gpu(cpu temps, with the psu fan turned upwards. Today i learned something, thanks :-)
this is the most unexciting tech series. I love it!
just binging while doing an assignment and was wondering where the piano was coming from. oh luke why HAHAH
It makes huge difference in difference scenario, or if you have a silent PC with GPU 0 rpm on low load. this video only tested the scenario that has no effect on external fan since your case is already cooled with other fans.
So here is the case this will make a huge difference:
- Case with no fan + CPU Noctua fan + silent GPU. = > big difference since the power supply will take the hot air out.
This question would have been asked before, good job addressing it. Safe to say you would have answered many peoples questions, which is the purpose of all these videos Luke has created for us. It doesn't matter how 'stupid' you might think the idea behind the video might be, I can guarantee you all it has still helped someone.
It would have been nice to do a comparison when the unit is sitting on a carpet. I remember Linus mentioning it in a build video, so it's worth testing.
I'm kind of surprised by this. When i did an upgrade in January i had huge overheating problems until i moved around the cooling a bit.
previous: fans at the top/rear of the case exhausting air (one of them one of those closed loop AIO liquid CPU coolers), a 6950 (outputs all air out of the back of the card) and the PSU pulling air in from a vent at the bottom of the case. One fan at the front pulling cool air in. all was fine
After upgrade: same as before but a new r9 390 which vents all air into the case. result - huge overheating of the GPU with it's fan hitting 70-80% speed and sounding like a hurricane. the side panel at the bottom of the case was getting noticeably hot to the touch.
turning over the PSU so it pulled air from inside the case did help quite a bit, but the GPU was still running hot and loud. I eventually completely fixed it by adding another intake fan at the front-underside of the case to pull in more cool air to that area.
Any sort of fan/airflow orientation will work if the PC stands that high up in the middle of a table in the middle of the room. Less dust, further away from the wall.
Nice video but that song brings back memories of being on hold on the phone to a well known computer part website.
