I had contacted customer support who advised me to post on the forums about this issue.
The game is causing my GPU to overheat and crashes my whole PC making it non-responsive.
I never had this issue before with any other game except this one, I don’t really appreciate it as GPU’s aren’t the cheapest, would have assumed that this would have been thorougly tested before you launch a beta to the public.
Are you running wallpaper engine? I have a topic posted about the issues I’ve run into with d4 and wallpaper engine interacting in weird ways causing d4 to run terribly, lock up my pc, and crash.
Try setting FPS caps in nvidia and in game. Worked with my MSI 3080. Careful with time spent on vendor screens; for whatever reason that will redline it. Obviously that’s a game issue.
I was having the same issue. GPU would constantly stay at 83-85c then crash my computer even with the fan curve running at 100% sounding like a jet taking off. I’m running a 2080ti and 1440p monitor with 144hz refresh. I tried lowering the settings to lowest allowable settings and still crashed from overheating. I did end up figuring out that if I capped my fps to 60 in game I could run everything at max and temps stayed at 60c roughly. Hope this helps anyone!
83-85c for a GPU is nothing, They are rated for higher than that. Honestly, you can actually run your GPU all the way up to 100c without issues. If your PC is crashing you have another issue that isn’t D4 related. I would actually use event viewer and see what is crashing the PC, or why its causing D4 to crash.
But there is something wrong with this game. 
You have hardware problem, why post here? I suggest that you improve your cooling, change graphics card, or decrease power available to the card using any OC tool. Your issue has nothing to do with Diablo game.
Yes it does. If it works great until one beta and everyone has the issue the common denominator is D4, not the cards. My card doesnt even get used just tries to burn my cpu and memory. The GPU sits at 0%. Drivers are up to date.
This thread is about some dude card overheating, clearly a hardware issue which has nothing to do with the game. Common denonimator for him and other dudes is brand new, extremely demanding game which shows how poorly built their hardware has been. Again, no games’ fault.
And you come here and say that your GPU usage sits at 0%, I suggest you create your own thread and cry there.
Lol I think this guy cant even tell the difference between CPU and GPU. 
actually, I can, and 85c on a GPU is NOT bad. Nvidia GPU temps under 70 to 85 °C are considered the normal range, Taken from Nvidia’s own page. Want to try again? also, your GPU just isn’t a graphics processing unit, they have not been that way since the early 2000s. All modern GPUs today are GPGPU. Meaning they are capable of running more than just the graphics pipeline. You would know that if you understood anything.
Once again you can 100% run your GPU up to its maximum rated thermal limit 100% of the time and the card will work fine. That is what they are rated for. 83-85c is 100% normal for a GPU Nvidia.
If your PC is crashing with normal temps yes you 100% have an issue with YOUR pc it’s not the game’s fault. Try harder, next time clown.
Lol, I think this guy can’t even tell the difference between CPU and GPU.
imagine in 2023 thinking the only thing GPUS can do is run graphics lol.
And yet whenever I open a vendor screen I can watch my card in real time climb 20 degrees and the memory clock redline? That’s not a card issue. A vendor screen should be the least intensive part of the game. That’s coding.
Of course, Blizzard can optimize this. Lower number of polygons, or whatever is demanding so many calculations exactly in that place in the game interface. Point is, hardware should not brick, melt, overheat, or fail when displaying whatever game asks is to. GPU must respond to all requests, like CPUs do. CPU does millions and millions of calculations, even with all cores saturated to 100%, and we don’t hear about CPUs overheat or melting, wonder why that is 
Running anything at a maximum intensity be it machinery, component, human, etc will eventually fail if that intensity is generating heat. Heat breaks things down.
So if you have designed your game in a way whereby it causes a common component to reach and stay at maximum intensity—utilizing the designers recommended/auto settings, that is most certainly the fault of the game designers.
High Texture files are extremely demanding. Turn them down to medium or low.
Cap you FPS as well. Ensure your Windows page file is set to auto.
And under gaming load 70 to 85 °C is normal temps for nvidia without water cooling.
I have same vendor temperature issue(3080ti here) - medium textures didnt help at all, also tried disabling distortions and some other options - no effect(fps capped, power limite enabled). Also, 2 of my friends also have that issue(3080 and 3090).
