Stated when i start the pc..saying something like "fan not detected,press F1 to continue,F2 to setup utility"

It was there since my previous fan has malfunction, now i change a new one ,and yet is still stated there..

the fan is working fine ,though is bit noisy..

download some software namely speedfan and pcwizard ,trying to get into some fan control options ,but the software too dont detect the newly installed fan..

please help me to solve this problem..

thx in advance

It comes with three wires...

if the fan plug is rightly able to connect into somewhere in the cpu, i guess that must be the cpu fan header plug..

and no, it wasnt connect directly to the power supply ,it is connected to the mobo
