I'd just hook it to a seperate switch. That way you can keep it on after your PC's off to cool it down a bit...

If you want it to come on / off with your system you'll need either a power supply with an accessory outlet on the back or you'll need to install a small relay (SPST-NO, 12V coil) in series with the AC supply to your pump and connect the coil to a 12V source on your power supply.
