Hi all,

Wondered if I could get some opinions on a new issue that has cropped up in the last week or so with my GPU.

For some reason, the GPU fan seems to just go absolutely crazy for a short burst of time. It hasn't done this since I got it, just literally the last week or so, and nothing has changed as far as I am aware.

Here is a sensor log I pulled off when trying to replicate the issue which demonstrates the RMP change:

Does anyone have any suggestions about cause and resolution for this? I could appreciate maybe it would happen if the temperature becomes excessive but the log file (which is every 5 seconds for 2 hours) suggests that the temperature of the GPU stays pretty consistently around 84.00°C.

Any advice/guidance would be appreciated :)

Thankyou!

It's more like 30°C when idle, this is literally a few minutes into starting a game (elder scrolls online).

Honestly even though it does seem a bit hot, the fan doesn't kick in consistently with the temp being at 85; it just has random intervals where it does it (kind of assumed it would always be at 5000RPM if it was temperature based).

When was the last time you updated the gpu driver or are they set to automatically install?

@SpyderTracks They are set to automatically install (and were updated quite recently), but I also tend to run manual scans on them as well to be sure. I did apply driver updates yesterday morning but I don't think they were GPU related.

I actually found an alternative way around it, and that was to introduce a manual fan curve. Looks to me like the fan speed was sitting at about 50% all the way up to 80degrees, and then at 85 it ramps directly up to 100% for a few seconds then goes back to 50% again. Rinse & repeat. Not sure why a GPU getting close to 80degrees is set to 50% fan speed but hey lol :)
