Question GPU fan reach max rpm randomly

[Erithlor]

My GPU fan started to act weirdly in the past week. During gaming every 2-3 minutes minutes one of the GPU fans reach max rpm, it stays like that for ~10 seconds then stops for a second and then back to normal for 2-3 minutes. It also ignores Afterburner settings. If I set for example 50% fan speed manually it still does that max spin thing every 2-3 minutes. I tried to unplug the fan, but if I do that then the other two fans on the GPU start to do this.

This happens only during gaming. If I set GPU speed to 50% and leave the pc idle, it will stay like that.

What could be the problem? GPU controller is dying? Bad driver?

My card is rtx 2080 ti. I bought it two years ago. There are no dust, all temps as usual.

You could try and uninstall your GPU drivers using DDU and reinstall the drivers with the latest sourced from Nvidia's support site. Manually install the driver in an elevated command ,i.e, Right click installer>Run as Administrator.

Also check and see what version of BIOS you're running for your motherboard. Speaking of which, list yours full system's specs.
