Question GPU usage low but temperature very high

[zainsvibin]

So I've had this PC for almost a year, and everything was going fine till 2 days ago one night i was randomly on my PC and an error occurred, showing that blue screen. After this incident, some things changed. My gpu temperature would go very high even though it's usage was below 10% while the temperature was 90-100 degrees Celsius. And keep in mind this was without playing any game, just Google Chrome loaded up, nothing else. I searched for some solutions, installed the latest gpu drivers from GeForce experience, reinstalled the gpu drivers today. There isn't any background program or anything causing problems as I checked in task manager. This problems gotten so bad that today, while using my PC, my Monitor went into standby mode because of the gpu temperature, which reached 101 degrees.


Here are my PC specs:
Asus rtx 4090
I9 13900kf
4 tb ssd
36tb hd
Asus prime z690
64gb ram
Phanteks nv7 casing

Monitor : Samsung g8 odyssey
OS: Windows 11

Thanks in advance.

Are you looking at gpu hot spot? The limit on the 4090's gpu core is 88C. I believe hot spot is up to 110C.

Someone's gonna need to put some fresh paste on that gpu die.


Since you have a 13th gen i9, the crash could be related to the recent news of 13 and 14 gen Raptor Lake cpus; defects/oxidation/too aggressive boosts/voltage... there's no solid culprit at this time.
If you haven't updated the bios lately, you should at least do that, as board vendors have been releasing updates that force the defaults to run to Intel spec; for the longest time, most Z boards' defaults have been overclocks.
There's supposed to be a fix coming next month: https://forums.tomshardware.com/thr...-root-cause-fix-coming-by-mid-august.3850099/
