Should you mount your Power Supply up or down? 

always remember every rgb fan boosts your pc by 25% (120mm) or by 35% (240mm)

@@stunt_niklas452 And add a few tiny degrees heat inside the case. Always better during a very cold winter though...

What exactly do you mean by affordable? 50€? 70€? 100€? I have a seasonic focus plus gold 650W which I got for around 85€

@jackthegamer I'm in the process of building a computer for a blind friend. He has no use for pretty lights, but with the money he had available (spent just over $1k), I ended up having to buy some of the parts having LEDs. Now, if only I can find the power supply I'm giving him...it doesn't have LEDs.

I went off the advice of a friend and spent £100 on a gold efficiency psu that only draws what it uses not the full wattage

How about what gigabyte fucked up in the 10th series g1 gaming cards? I know for sure that 1070 has a fan issues like mine rx 480 which results in 1 fan sounding like rotor when first starting,also the insane temps on the rx 480 even after the bios update.I really wish I could make something about that cuz that card can't even hold the advertised clock on the box,it's always going up and down but never stable even on 72-3 C

JayzTwoCents

Hi Jay, basic subject I've been meaning to suggest - what kind of temperatures we should be seeing inside of a water cooling loop - when we have a single pump and res config for say - 1 CPU and 2 GPUs (1080 GTX?). What would be the ones we'd expect coming out of the rads, after it comes out of the GPU blocks, CPU block, etc. An overall overview of water temps in the system.

That Def Leppard reference :D

If we put the unlikely posibility of a pressure issue(dust entering without passing filter) aside, your system overall will likely benefit from this way of mounting the PSU. Here is why; If the fan facing down is the normal way, then the electronics that produce heat inside the PSU will be mounted on the side facing up into the cabinet. The heat will then travel up, away from the fan, potentially get trapped between the electronics and the metal plate and heat it up. By mounting it with the fan facing up, the heat will travel up towards the fan and heat said metal plate less, in addition the previously warmer plate now face outwards against the cool air under the cabinet. All in all I don't think it will make a noticeable difference and either way of mounting it is fine. Exception for the water cooled systems.

Tom Julio Such a vacuum xD ...get it, negative pressure, vacuum... Please tell me I'm not the only one...

You're right. As always, he's awesome :)

What scientific proof do you need? If you draw more air in than you remove, the air will go out through the crevices of the case, thus resulting in less dust accumulating. You don't need "scientific testing" to verify common sense.

Without proof all you have is theory. Have you measured the amount of dust present in a case with positive pressure vs a case with negative pressure? If not, how can you be sure one is better than the other. Also, last I checked you are not Jay. So my comment was not directed at you.

+James Rhodes I've already does this test about air pressure with smoke

James Rhodes I doubt there are many who would bother with that because a) it's something that is intuitive to most people, and b) experience confirms it but hey, good luck on finding those test results!

Do you have a video up? If so I missed it. I would like to see it. If not, maybe you could do one. I think it would be interesting to see.

Sick Corsair SF750 badge to display: fan down.

Mine is about 75 max unless the ambient outside is warmer than usual like peak summer, out of games 35 max, although I'm not running much from 2018-present

@Orion 8096758 if you have the right case fans the inside of you pc will not be warm. mine is generally about the same as the outside room temperature. (two front fans as intake, two top fans and a rear as exhaust)

and i know this as a fact as there's a temperature sensor inside

@Orion 8096758 He actually did address that with the entire circulation conversation when he started talking about the fan being faced down, he just didn't word it as such.

47 max here, though is that normal with older hardware?

Exactly the same!! On my next Pc ima build one and all these videos are very VERY!! helpful 😅

Well?

Did u build it?

Pc update?

Lay PC down if you doing work. I have 3x A12x25s at front. Air only in via filtered front. Air out via rear fan, GPU vent and PSU. Every other hole, no matter how small taped up, even PCI slot cover holes. PSU fan is hybrid and never needs to come on. The positive pressure from front fans is huge and is almost enough to blow lighter flame out if placed near psu vent. Front fans dialed in with noctua fan controller. Highest speed without being audible in dead of night. GPU is always 'actively' cooled via the flow too. Clean case, silent, cool.

Lucky it was just a screw, if the P/S was the right way up passive air flow would do the work, cooler air falling as warm rises ...

Same happened to me. That's why I'm watching this video 🤣🤣🤣

@@backutZR lol

Orion 8096758 I mean I’m pretty sure that the fan facing upwards is an input fan and the warm air is pushed out the back (I think)

@@Ethan-rz6cx You are correct intake side on top with heat exhaust going out the back of the unit. In my recent build I had no choice but to place the intake down because of separate enclosure for power supply draws air from below. Without the enclosure I would have gone intake facing up, just to draw heat from inside the box out.

When the PSU is sucking air in from below and letting it push itself out the back, there is still a suction pressure from beneath that will make even the hot air go down. You are correct that hot air rises in cold air, however, the rate at which this happens is far slower than you may expect, especially when we are talking only a few degrees difference.

Sirei Talk Ouch.. Any update now? How did it hold up? Watercooling is still a constant gamble it seems, I’m always paranoid about it, considering I got myself an AIO for the first time Fans facing down from now on 100%

@@Glossah Everything's fine now. Only the PSU was damaged luckily. I've been running the AIO since, and it's been working great! 👍😁

@@evieamity7471 is an AIO worth the risk of leakage and water damage? Also how is maintenance on an AIO?

@@computethis7128 Mine hasn't leaked, so I can't really say whether it's worth it or not.. But so far it seems worth it for how beautiful it looks and for how well it performs. There really isn't any maintainence to be done since the liquid inside is never exposed to anything.. though I don't know for certain if it would ever need to be done.

@@evieamity7471 what about corrosion of the pipe over time from the flow of water? And which aio do you reccomend?

You realize that fans in a computer case are for cooling. Warm air rises. Why would fans be more effective blowing down? (this is not an actual question and is very sarcastic)

@@paulmartin2348 There are new fans that blow in the opposite direction so they work OK blowing up. But the mechanics of the fans are such that it is much more effective (and thus quieter) when blowing down, against the gravity. If the fan blows up, it is resting on the O-ring that holds the spindle. Plus the air pressure. The convection is not a factor in a case, there is far too much of air movement inside. The fans can easily overmatch the convection.

1200W? It's a 600W PSU....

Cooler Master NR600. I should mount down? Using a Fractal Design ION+560

DKC you sir are now the donkey of the day 🤗

And I just used the foam packaging to keep my case stably raised above the carpet and make it easier to pick up to work on it.

No, he mentioned it depends on where you're planning on putting your tower, if you put it on a carpet floor with no case feet, fan facing up is ideal unless you want to blow up your PSU. And a few more things. edit - posted that comment before Jay mentioned carpet.

It doesn't make any SIGNIFICANT difference. Though if you're building you might as well mount it accordingly and optimize since it's not hurting you or your time. If you're putting it on carpet, face the fan upwards. If on hard surfaces, face it downwards to help keep dust out. And Jay made a good point I didn't think of, watercooling and potential leaking into the fan could cause a potentially, VERY bad day. But in the end it's not a big deal. Kinda like how people freak out over not having anti-static mats/wrist bands, people go their whole lives without static discharge frying their equipment but it's a nice practice if you don't want to take any chances.

Well yeah, the static discharge is a bit of a scare, but so are many other things like smokers falling asleep with a burning cigarette and getting set on fire. Maybe not the best reference, but the chance of that are very slim, yet it could happen and if it happen the consequences might be serious. I started wearing the wrist straps just to be sure, tho following basic guidelines like evading wearing too much and specifically e-static prone clothes like wool sweaters and shit. Not saying to build half naked or fully naked, tho that might be a really fun idea if you're building with your gf, tho the build might turn slower than expected then, but hey savor more moments. :P And again, sjw's and feminazi would be triggered so that would be "sexhist"... -_- Which is only another reason to do it. :D With your bf/gf's consent of course. Which is pretty much inherently self explicit, hence we don't really live in a rape culture. But I digress. xD Pretty much you can decide about your PSU given your environment. I personally would rather install it the normal way and not have dust fest fluffy carpet, especially if you're allergic to domestic dust [acars/mites]. Or you can simply put a nice platform there, but srsly, those carpets aren't really that good in general if you're gonna leave your pc on the ground. You will still get more dust compared to a flad surface, unless you don't mind and can vacuum it more often than the other stuff.

Basically, I think what PSU you are buying is much more important than what way you will put the fans. Also, although it's better to get a "bigger" psu in terms of power, [you'll also shouldn't buy bigger but crappier psus], with processors [cpu + gpu] getting ever more efficient, you don't need like +1000w powerhouses. You can easily get away with anything from [400W if very good, 450W if decently] like 500w - 850W, for the average [gaming] user, I would say anywhere around these estimates, depending on what you want to do with it. More particularly running multiple gpus. I generally prefer the strongest single gpu than bothering with sli/xfire. As for the newer api way, which I think is much better idea, tho I don't think I will be doing this any time soon neither, and my reason would probably be if I could/want to run two cards and get benefits from exclusive features, without having to have a separate system to benefit from them. And/or you could bring some enhancement in performance without any harmful disadvantages. But that being said, you are better buying a tougher more quality PSU, than going for the sole higher wattage. It's a good idea to go higher than "needed", as long as you don't need to drop the efficiency rating. Sorta like a thumb rule. Better get a quality 650W Gold [some like the SeaSonic and CoolerMaster are gold, but nearing Platinum] than going for a 750W Silver / cheaper quality. But honestly, that's just my preferences and these days, unless you are buying some really trashy PSU from some weird brand you will not have regrets. :P

except it does make a difference

The PSU may suck its exhaust air back in if the PC is close enough to a wall. The exhaust air out the back will hit the wall and scatter in all directions, including down to where the intake will suck it back in. I doubt the small amount of warmer air would have much of an effect on the overall temp of the PSU. The amount of warm air as well as all the cool air would make the intake temp effectively ambient anyway.

Then you don't have to worry about whether or not it gets ventilation.

That was happening to me with my built. The hot air from the case was f*** up all my PSU until one day I decide to flip it down and from then on never encountered air flow problems with the PSU.

Yes ,that's why psu manufacturers always recommend fan down, it's nearly always better to intake fresh,filtered air for PSU ,CPU and GPU and let case fans exhaust hot air from case, positive pressure also helps as it forces hot air out of the case as well as reducing dust.

It doesnt really matter, its not a simple as 20 plus 60, the only thing that actually changes kinda noticeably is the airflow, but then again... it doesn't really matter...

Niko_2142 front fan takes in 23c and gpu makes 60c then you have let's say 50c in case. psu takes in 50c and blow it out. compare to take in 23c and blow out let's say 30c. so take air from outside case is cooler for psu so it shulde be better for it?

Uh... No. taking hotter air doesn't mean it's ability to carry heat is reduced. But if you are worried about your config, just don't, the important part is air getting where it needs to be, not if it's hotter or cooler, no one has ever had any issues, and as long as your psu is fairly decent, it just won't matter.

Niko_2142 overall it is better to have psu fan take air from outside of the case for the best temperature. I got my 1000w fractal r2 psu. I not worried about my config. I did just state this becuse jay did say it will take cooler air from inside of case and I don't think it will do that, prove me wrong. and I know that many ppl include me time to time will so what he says on the video.
