From what I've read (corect me if I'm wrong) to make the 12V fans run at 7V all I have to due is swap the two wires, red and black on fan, or yellow and black on the p/s connector, corect? Would I be able to do this with a fan connected to a 3 pin motherboard conection by just cutting the black and red wires and crossing them? I have a Blue Orb on my Geforce card that I'm thinking of doing this to, will it affect the moboard at all? Any help would be great! Thanks.

Don't cross any wires on your MB headers..if you want 7V use a connector off the Power Supply and connect your fan to a 12V yellow and a 5V Red for a voltage of 7V.
