I just got the Nvidia GTX 470 and it has a zalman heat sync and fans on it that requires its own power. It uses a normal 3 pin power cable. My question is are there any 3 open 3 pin connectors open and available for use on my Mac Pro 1,1 or am I going to have to by an adapter? I have a free ide power cable and I also have the molex to data adapter cable. So if there's anyway I can convert one of those for power to this fan that would work too. If there are adapters available like that, where can I get one? Let me know and thanks.
