You can "hotwire" a computer PSU by using something to short the green wire to any of the black wires on the 24 pin Motherboard connector (the big one) This does the exact same thing as the power switch on a computer. If you want to get fancy you can wire a switch in between those 2 pins.

You can buy PSU jumpers which do what I said in my post above. they will work on any ATX style PSU with a 24 pin connector

Another option is to get something like this:

This is an external power supply unit that has a single 4 pin Molex connector. You can then use converter cables to 3 pin fan headers, or whatever standard power connection the fans are using. You could even plug this into a fan speed controller unit then the fans into the speed controller.
