Question Screen goes blank and fans ramp up ?

[MaxiJOO]

Hey!

I am experiencing some troubles: In my system I have a 12900k and a Zotac RTX 3080 Trinity. The System has a Seasonic Prime 750W PSU. (and no, the issue is not the psu)
My issue is, that whenever the GPU is hit with a rather heavy workload (Rendering H.265 in Premiere), the screen goes blank and all the fans in my system ramp up to max.

I did some monitoring and found that shortly before all the fans ramp up and the screen goes blank the GPU's temps are around 70° C/158°F. The issue also rarely occurs when playing games.

My question now is, could it be that the manufacturer of the GPU messed up with the thermal paste on the chip(Card get's too hot before I can even get a propper temp reading?) or could it be something completely different like a malfunctioning driver? - What causes the screen to go blank and the fans to ramp up? [One more thing: Sometimes, after the "crash" the screen resolution is sth like 640p and in Windows device manager the GPU has the staus "Windows has stopped this device because it has reported problems. (Code 43)"] {Running Windows 11}

Please help me out with your knowledge!
Thanks,
Max

Welcome to the forums, newcomer!

How did you rule out that the PSU is not the issue? The RTX and RX cards from both camps were known(revealed) to draw much more power than what was advertised by Nvidia and AMD and what was stated on AIB maker spec's page. Not all games will tax the GPU(and CPU) the same way which is why we ask for a list of titles you've taxed the platform with. Rendering will also vary from one user to another.

We're going to need a little more information. Please list the specs to your build like so:
CPU:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:

Do mention the specs in detail or with links if you're unsure what to include. If the PSU has been in service for a while, include it's age. BIOS version for your motherboard?
