SOURCE: asus p5gc-mx/1333 cpu fan error

There are usually three wires on a fan to connect to mother board 1 red "+" positive, 1 black "-" negative and 1 yellow which feed the bios with information about the fan, i.e. how many rpms it is running at. To check the fan you will need to open the pc by taking the side panel off, you should do this when the computer is running or you will not be able to check the fan is working or not, but be carefull not to touch anything inside the case. If the is not spinning check the cable is in the socket properly by turning the computer off first, if it is you will need to replace it, other wise the processor will burn out. If the fan is spinning then the bios is not receiving the infornmation from the fan, therefore you need to shut down the pc and unplug from mains and check the cable(give it a littke wiggle) and make sure it is making a good connection, try blowing any dust of the connectors, power the pc again and if the bios is still giving you the same message you will definatly need a new fan, you can by them from any pc store, take the old one with you to ensure you get the correct size fan.
