GPU Hot spot temps too high on 6800XT?

Hi,

Im looking for some advice on my GPU. I have never really had any issues with it, but I have been playing through the campaign of CoD:Modern Warfare II during last few days. The fans have been quite loud but this is not unusual when playing fairly demanding games, and not sure that the Gigabyte gaming OC model has the best of coolers on it. I play on a 3440 x 1440p ultrawide. The CPU is cooled with an NZXT AIO and temps are great, and there is also plenty of airflow in the case.

What was unusual is that I have been experiencing quite a few crashes in the game where the screen goes black, the fans drop down and i have to hard reset the PC.

Id noticed that the GPU utilisation had been at 99% which I guess might not be that unusual but because of the crashes I decided to run HW Monitor so I can check the GPU temps.

GPU Temperature

Min:- 39C
Max:- 79C
Average:- 70C

Memory Junction

Min:- 42C
Max:- 76C
Average:- 68C

GPU Hot Spot Temp

Min:- 42C
Max:- 109C
Average:- 95C

The GPU Temp and Memory Junction don't seem too concerning, but the the Hot Spot Temp hitting close to 110C seems very high. I know this will be the hottest part of the card, but even so this seems quite high, and I wondered whether this was contributing to the crashing.

Has anyone noticed extremely high temps on this card, either generally or whether this might be an issue with this game only. I've never had any game crashes running games like Cyberpunk, Hogwarts, etc.


You think its worth a repaste of the GPU... I already have a tube of Thermal Grizzly Kryonaut so I dont have to buy any, but will this have little impact?

Thanks

Not overvolting, undervolting. Slightly lowering the volts can actually be seen to show performance increases as lower volts = lower temps = longer/higher boost performance (to put it in its most basic form)
Well worth having a look at some YouTube guides and may well fix your problem.

Had a couple of crashes now in Diablo 4 to which I wouldn't have thought was particularly GPU intensive. Hotspot temp wasnt quite 110 C though, at this time max was about 105C. I'll find some Youtube guides on undervolting in the Adrenalin software to see if it sorts the potential problem.

Trying to think if any other configurations have changed on my PC but nothing significant springs to mind....only recent non gaming software I installed was Rainmeter to customise my desktop. I had used it previously though and dont recall any crashing.

Will go down the undervolting route, and might just repaste the GPU anyway, figure it cant do any harm.
 
Ok thanks for all the inputs, really appreciate it. I'll try the undervolt first and assess my options from there depending on the result.

I have repasted a card before so fairly comfortable with doing that. I did it with the 2080 that I had previously and temps dropped by about 5 degrees if I recall.

Before this, I will also investigate potentially RMA the card too with Gigabyte. I only purchased the card last July, so seems a little early for paste to have degraded.
 
Thanks, will get to some testing tomorrow and let you know. Quick question, what do you guys use for stress testing GPU’s? I have a 3D mark license to use Timespy, etc. Are there any other good options?
 
Ok, so I undervolted the GPP from 1150 to 1050 mV, which caused crashing when running Timespy and Timespy extreme. I raised this to 1080 which seems to be more stable.

Furmark seems to have the hotspot now hitting 105C but my last run at Timespy Extreme the hotspot in HW monitor peaked at 111C, so thats a 30C variance between hotspot and standard GPU Temp at 81C.

So im not sure where I am now....seems like i should contact Gigabyte to look at RMA
 
My case is a Phanteks P500A. Case airflow seems good. I have 3x 140mm front intake fans, 1 140mm rear exhaust, as well as a 140mm at bottom of the case blowing air into the GPU. Roof of the case has the fans and radiator of my CPU AIO set to exhaust.

I think I'm going to go down the warranty support route. I actually purchased the card from Overclockers, but as I'm just outside of the one year period, guess I will have to use the Gigabyte process, so hopefully they are not a pain to deal with
