I'm on the last stages of putting together my first comp. its been sucessful so far, but i'm at a fix. coming out of my psu are the usual assortment of wires, but there is also one wire with a three pin input. it looks like the power pins for fans. is this the connection for the power supply fan? it is composed of one black and one blue wire if that helps. thanks for any input.
