See if some thing is struck in the cpu fan, just switch off your computer and try to spin it with your fingers if it works fine then check the power connections and attached the cpu fan cable in system fan or chassis fan header if works then fine else
It simply means that it is a time to get a new CPU fan installed.

Check the CPU fan header. Last time this happened, I plugged it into the CPU_fan2 port and disabled the CPU_fan header and it worked. Or try a normal fan header.
