My GPU’s fans spin either at 100% or stand still. they rarely ever dip below 1000rpm, and if so, only shortly (see images below). This worries me, and I am 99% sure I’ll refund that card, but before buying a new one, I want to make sure the fault is not with my system. This is my first AMD GPU and I am pretty green in Linux.

So far I tried adjusting the GPU’s fan curve, with fan-control and CoreCtrl but it didn’t change the erratic fan behavior.

I checked my BIOS for 0rpm mode, but couldn’t find anything. It also only let’s me configure CPU and sys fan curves.

Is there anything I can try before sending the card back to fix these issues or -best case- verify the card is actually causing the issue? I’d hate to get a replacement and face the same issues again.

Update I REMed it and will get the same.card again, but from a different, more widely adopted vendor. I don’t want to spent another week troubleshooting an issue I may not have the skill to fix.

Thank you all for your input :)

    1548 RPM should be slow for a small GPU fan, no? My Nvidia 3090 behaves exactly the same, switching the fan on and off as it hovers around 60C or so.

    Looks like it’s working fine to me.

    Also, take linux GPU monitors with a grain of salt. It’s possible the GPU fan RPM measurement is totally borked, and it basically represents “on” or “off.” Check it with your eyes and ears instead, see if the fan is screaming or not. It shouldn’t be below 76C (as modern GPUs are configured to operate above 80C or so).
