2080RTX at 85c at 99% usage

[JayEee]

Hey guys,

 

I have a 2080RTX running at 3440x1440 in a Silverstone GD09 flat desk case and when I play most modern games (such as Call of the Wild) the GPU runs at 99%.

The GPU Temp is 85c at full load which I think is a bit too high after doing some googling, just wandering if its going to affect the longevity of the card. GPU idles at 42c at 0-3% usage.
Would adding an inward flow fan at the back near the PSU make any difference? I think its a 120mm size.

 

Some info:
I have already cleaned all the dust out of the case filters, GPU, and CPU.
The 2080RTX has only one fan at the far end.

I tried running the GPU in the 8x slot but it made no difference.

CPU fan is a low profile Noctua.
DVD drive opening is blocked by that foamy plasticky material on the left.

The two fans at the front are blowing air inwards.

I found out that one of the front case fans (the Noctua on the right) was actually blowing air outwards, so I flipped it over to blow air in instead, no difference with the GPU, but the CPU is now 5c cooler.
Nothing is overclocked, XMP is disabled because Hitman 3 was crashing in XMP mode.

HWMonitor screenshot is when COTW is running. VSync is on at 60FPS (my monitor can only do 60FPS).

Yup.

Nope, that's what I'd expect that card to run at, and it's perfectly fine. Nvidia cards run at ~84C at all times and adjust frequency and voltage to keep it there. Unless it's getting above 90C, it's running at Nvidia spec and perfectly safe.

Your temps aren't actually (too) high, but yes adding another fan in the slot by you PSU will help get fresh air to your GPU. Clean up them cables too, try to make the path as unhindered as possible. That should force all the air out the back of the case.

hmm perhaps I'll install a fan and see how it goes

ok, ok interesting. So nothing to worry about. Good to know.

ok I'll install another fan and clean up the PSU cables.
Would be nice the run the GPU at a few degrees cooler.

Yea like others have said, your temps are fine, but cooler is always better!

[JayEee]

ok so when installing a new rear fan next to the PSU, should it blow outwards rather than inwards?

If it blow inwards, wouldn't the GPU get fresher air?

On the other hand, since there are two large fans at the front, all that air would need help to dissipate, instead of escaping out through all the small holes in the casing and PCI-E covers.

Perhaps I'll try both ways and see which one is better.

intake.

It'll probably still run at 85C, but it'll boost higher.

Ok I'll go for Intake, makes sense to flow fresh air towards the GPU. I'll probably try exhaust just for laughs, but I think intake would be better.

I'm wandering if its worth removing some of the PCI-E slot covers so the air can escape easier  

Three 120mm fans pushing air in, but not much exhaust flow through the tiny holes
Good to know that 85c is the controlled temp, thanks.

I would mess around with it. Intake is most likely better with the set up you have. 

Taking the covers off would probably help airflow, but just another thing to mess around with! have fun!

83c after installing the rear fan as an intake and clearing the cables as best I can (not much space to route the cables in my case).

2c difference, better than nothing

What nobody mentioned was that your GPU seems to be a blower model. They generally run warmer than a non-blower cooler. It also explains why adding a fan near the PSU did little good. Not much you can do other than changing the cooler on the GPU, but really not worth it in my opinion.

The PC Case is a flat desktop design so no space for water cooling.

But I trust nVidia limiting it to 85c so it should be fine.
ps. I've had many nVidia fan cooled cards, none of them have ever failed.
I may get slightly better performance with water cooling, but meh, I'm not fussed about 10% performance TBH.
My monitor is limited to 60FPS anyway lol
