It's my PC, desktop.

I have an Asrock motherboard which does not seem to support Linux so none of its sensors show up in any thermal control app. Fan speeds and temperatures are just not there.

I can see everything else though, CPU temps, hard drive/NVME temps as well as memory temps.

I can see my GPU temps and fan speeds, but lately I cannot control the fan speed. I was using Lact to control it but I keep getting error messages in it and now it seems to take my changes but does nothing. Set fan speed to whatever I want and no change. Sits on 0 RPM.

It's an AMD GPU.

I set up some fan curves for my system fans and CPU fans in BIOS, but no idea if they even work in Linux or if they are being overwritten.

My old laptop omg... I had to manually add Linux as a boot option in BIOS because it just will not detect it as installed even when it is the only OS installed and taking up the whole drive. I tried a few distros and they all did the same thing, where these distros used to work.
