Replacing the cooling on an Antec P180 with Enermax TB Silence UCTB12P

Hey all, I just tossed a new system into my old Antec P180 chassis and am looking to keep it cool and quiet. The case has two 3 speed manual switch 180mm fans on the top and back which I would like to replace with a pair of variable speed Enermax TB Silence UCTB12Ps. I am not an overclocker so I am more interested in quiet than hyper cooling.

So my question is...
Is there a way to match the pin leads on the Enermax fans to the switch on the case, or maybe better can I use the motherboard connectors and skip the switch all together?

The motherboard is a ASRock 970 EXTREME3 AM3:
