Computer keeps shutting down due to 7800xt temps
Specs:
Radeon 7800xt
Ryzen 7 9850x3D
Corsair 2x16gb DDR 5
ASUS X870 P-Prime WiFi
Lian Li Edge 1000W
I just built the above computer and had a similar issue with my previous build. The only part I reused was the 7800xt. While playing my typical games my computer randomly shuts down completely with little to no warning. While running HW Monitor I can see that during certain cinematics or random moments of high usage the GPU hot spot will exceed 105 degrees C. Occasionally I will see the temps reach as high as 109 (GPU is rated up to 110).
Fixes Attempted:
Uninstalled and then reinstalled drivers
Undervolted GPU in adrenaline (preset)
Undervolted GPU in custom settings in adrenaline
Replaced the PSU (formerly 850w)
Reseated the ram
Turned down graphical settings in game
Games it has happened while playing:
CS2
Baldurs Gate 3
Cyberpunk 2077
(FPS always capped at <180 and happens at 1080p as well as 1440p)
