A little while ago my CPU fan on my PC kept switching from normal to high speed and back again. Then it just kept running at high speed. As soon as I turn it on the fan runs loudly. I checked the temps, fine (around 28-31 Celsius at idle) and the fan runs at high before bios. I tested it with a CPU fan from another pc, but it too ran at high speed. For now I linked the CPU fan to my case fan so that it can run normally. Is my bios or motherboard corrupted and causing this?
