I installed a NVIDIA GeForce 8800 GT video card in my 2007 Mac Pro to replace the ATI 1900 card, & now want to install a Zalman VF1000 cooler on the 8800. Problem is, the new cooler fan has a 3-prong plug, while the 8800 card has a 4-prong socket. I'm willing to cut & splice the original 8800 plug onto the new cooler, but there are 3 wires (black, white. red) on the new Zalman cooler plug, & 4 wires (black, yellow, blue, green) on the original 8800 unit. Help!
