    Anyone know the voltage of each of the power connector wires?

    The inside ones that attach to the HD and whatnot. There are 4, red, black, black, yellow. Thanx

    Yeah... bout' the only thing you wouldn't want to overclock, would be your clock...

    Red is usually +5 Volts, Yellow is usually +12 Volts, and black is ground.

    You will also find some -5 and -12 lines connecting to the system board.

    Thanx, I had an idea of moving my fan to the 12, right now its on the yellow. But 5 to 12 is probably way too much for tha fan to handle.... eh?

    I think you can use RED + Yellow for 7V on a fan.

    To keep the correct fan rotation try the red from the PS to the fan black and the yellow from the PS to the fan red. If the fan rotation is backward just reverse the wires.

    can someone please explain why 12V + 5V = 7V that section kinda baffled me in physics... Thanks

    Its all about potential difference, the "voltage" of a resistor (in this case the fan) ( no pun intended ), is really the difference of the voltages on each side (basically). So 12 and 5 yields 7, 5 and 0 (ground?) yields 5, etc. Hope that helps.

    This is kind of old, but still fitting:

    It said "requires Windows 95 or better," so I installed Linux.
