CPU fans nomally have just one connector - that goes to the motherboard - which picks up the power for the fan. It may have two wires only (power) - or three - the extra being the tachometer (speed sensing).

I can't imagine what other wires there are comng from yours. Fans do not normally connect to a connector on the wiring loom.

Do you mean it has a molex connector or a smaller one that can connect to the motherboard.
