Hello, I need a little help. I know, I know, why am I trying to put a square peg in a round hole. I want to install after market GPU fans on my SLI cards but the fans come with three pin ends. My cards have two pin slots. Original fans have black and red wires while the Zalman's have added a white wire. For speed adjustment? I would prefer that the cards determine fan speed. Is there and adapter or is it possible to wire the white with one of the other wires? If no other choice I will use a manual fan controller but this is not the best for me, prefer something that I can not mess up. Thanks for an help you send my way, John
