i recently installed a zalman vf900-cu fan on my xfx 7600gt. the zalman has a 3 pin connector (with black, red, and white wires) as opposed to the stock fan which has a 2 pin connector (with black and red wires only). so i currently have the fan plugged into the mobo by way of a 3 pin case fan connection. i was trying to adjust the gpu fan speed, but it did not seem to want to work. i was wondering if this was being caused from the fan being plugged into a case fan connection. and if so, i was looking to find out what the white wire of the zalman was to see if i could mod the connector to plug into the 2 pin connection of the gpu.
