The problem with this is that it would have to be an AT power supply, not an ATX which is what computers have used for years already. AT is a physically switched power supply...versus the ATX is software driven...no power without the motherboard telling it so. I thought of doing that and buying a pc based fan controller so I could vary the speed of the fans...but it was more of a hassle than it was worth.

You should be able to get a variable voltage adapter (12v) from some type of dollar store for about $7-$10. Make sure that it is enough to power both fans in mA...typical PC fans are around 250 mA.
