The pinout for the "Fan" connector is +12V and Ground. The +12 is the pin closest to the powersupply, or the pin on the left if you are facing the GS motherboard from the front end. Most fan wires are color coded, so the red wire goes to power and black to ground. >I pulled a perfectly good working fan out of a non-functioning 386sx power >supply.

The voltage rating is fine, the amerage level should be fine as well as long as it's not too high where it overloads the powersupply (I doubt that in this case). I've connected all sorts of fans to the "Fan" pins, back when I was trying to cool down my accelerator board. I had a 486 CPU mini-cooling fan in there (0.9W) as well as a full-sized fan pulled from an IBM powersupply, which had a higher power consumption rating. They were all DC +12V in case your wondering, it was just the wattage/ amperage levels that differed. You just need to slice the wires and stick them in a two-pin molex connector, I found one on a dead 80 columns card. :) Mitchell Spector spec@vax2.concordia.ca
