mother board : Afox 81.
There is no graphics card.
the problem:
The processor fan stays on the same speed :
when the computer is on, and even while the computer is idle too?

If you're using this fan by Molex to 3/4 pin, then that is normal. If no, maybe it is just programmed to work like that in BIOS.
