The pump assembly has the flying lead in which the fan plugs into, then the main lead from the cooler / pump assembly plugs into the motherboard header. You could plug into the cpu header but you would need to disable any fan contriol options in the bios for the cpu socket.
I don't like this idea to be honest!
the two wires.....just plug the fan into CPU only and put the pump wire into the POWER!
ok, i think its all done now, i will turn it on now (so scaredddd)
