Sounds like what I did with the fan in my IIe--poke a hole through the
power supply case and run a wire to an auxiliary power supply for a
12VDC fan.  (I originally tapped the +12 and GND wires leaving the
power supply, but I noticed that the fan slowed down every time a disk
drive kicked in.)

The GS motherboard probably supplies 12VDC for a fan.  It won't do a
thing for you if your fan takes 120VAC.
