Gpu running at 75cto 85c

[T3King]

I'm wondering how could I keep my gpu cooler I get those temps on overwatch. Running the gpu on max fan speed. 

How could I get better air flow I cant find anyway to get better air flow. I cant put aio on top because the mother board Z370-F foesnt give it enough space. Any tips guys. Muchify c case, mob z370f, aio kraken x62, 2 stock fans in the back cpu 8700k. Aio stopping alot of the airflow.

Did you try to set the rad as exhaust?

[Jurrunio]

how much does leaving the sides open help with temperature?

[martward]

You could try mounting the aio in the top as exhaust and move the two fans to the front as intake. Also orienting the PSU so it takes air from the bottom instead of the case can sometimes help, though I would only do this if there is a good filter in the bottom. Lastly purchasing good aftermarket fans can help (don't know what fans you have).

OP mentioned he couldnt mount radiator up top due to his motherboard getting in the way.    and as for my suggestion for temps as with your current setup maybe adding more fans on the radiator to make it push/pull might bring more air in the front and help temps a bit

Have you tried replacing thermal paste?

[Benjeh]

The answer is simple, you're pulling hot air into the case with the rad at the front directly onto the gpu, put your fans on top of the case to pull air in, then exhaust the hot air through the front of the case, the trade off means the cpu temp might rise by 1-4 degrees but your card will be a lot better off for it.

[emosun]

yeah your rad is blowing hot air on the gpu so what did you expect to happen?

[Firewrath9]

What fan speeds is your AIO at? if your cpu is chilling at 50-60c doing a not cpu intensive game, the fans will be barely spinning. Set them to 800-1200 rpm, and see new temps.

[aezakmi]

It's choking, get that side panel off and see if it helps. AIO on top will only decrease temp by like 2C and increase CPU temp by 8C so it's not worth. it.

 

I have 2 toasters and highest temp they hit is ~70C, case is the problem here.

Ok so I can't really be arsed to watch the video, can you type out what you're trying to say?

@T3King

 

Take an 80 or 90 mm fan, remove those lower PCI covers, black zip tie it as an exhaust under the GPU.

 

GPUs suck air UP into the heat sink.  You need to pull more air down under the GPU so its not respinning the HOT air its creating.

 

Also you are introducing warm air to your PC when your radiator is intake.  That's no Bueno for a GPU.  I would top mount that rad and not even try the rear PCI exhaust until I put in correct intake fans.  If you cannot top mount, than I would put a rear PCI exhaust in.  I do this on my Ryzen 7 unit because the R9 Fury would run hot if I let it.

You mean intake? how will it exhaust cold air into the gpu?

You're wrong, front mounted rad doesn't cause a huge increase in GPU temp.

Ah right, I'm sorry for thinking physics was a thing.... Care to explain where the heat from the rad magically disappears to? And where the GPU fans get their air from?

I mean exhaust.  You and anyone else can do tests to see that using it as intake and find out for yourself, or take advice from someone running 17 fans in 1 rig at 40% dead silence with temps only a huge loop can usually hit. 

 

Exhaust, because the issue is that the front intake is being automatically dragged up by Thermal Dynamics, and the upper 2x rear exhaust fans.  You can "re-direct" some of this air that's heading straight up, under the GPU - where it desperately needs it.

 

If mounted as rear bottom intake you get about half the drop in temps you would as exhaust, try it, do your benches and see for yourself

[Tristerin]

Its all about GETTING THAT HOT AIR OUT OF THE CASE AS FAST AS POSSIBLE SO YOU CAN AND INTRODUCE COOL AIR BACK IN THE CASE...AS FAST AS POSSIBLE

 

That's how to keep a PC cooled to the best effect possible, while maintaining dBA levels that are tolerable (or not).  Even a front mounted rad can work, maybe not optimal, but can work just fine - if that heat doesn't have time to build up because its being evacuated to quickly.  

 

Positive or Negative Air Pressure achieves this the best (killing Hot Spots)

The air coming out of a radiator may feel hot to you, but it's still SIGNIFICANTLY colder than a GPU. Even if the air coming out of the rad is 49C, that's still 36C COLDER than this person's graphics card. Thermal transfer only works one way passively. You aren't heating up the card, you're still cooling it.

Are you seriously using hot air rises as a point in this post? Air will move where you push it in a case because the volume of air is so low, this isn't a house. Oh and I have 6 fans and its dead silent.

[BetterThanLife]

The case honestly looks like a hot box, i bet those rad fans spin very slowly and barely push any air across your card.

 

Best bet IMO is to put a hole in your side panel and dump a nice 120/140MM fan so it breathes outward to remove the GPU's overwhelming heat.

Sure thing guy

 

Thermal dynamics yet you want to use the words physics in this same forum post.  Thanks bro but if you don't want to be educated because you know so much than we don't need to converse, I already know I am superior to you in understanding PC thermal dynamics.  I spend a lot of time and research on it.

so you're saying that the ambient air outside the case, passes through the rad, doesn't heat up? The rad is going to dump hot air into the case regardless of what my hand says, a cooler is only as effecient as the fin design and the fan performance combined with the ambient temp, the fans on that gpu are rotating air from within the case....

You may have had a point until you wrote that.

 

Stay humble and fight with good intentions friend.

Its not affecting it much - but it is affecting it.  The cooler the air in the equation, the lower the thermal equilibrium.
