    Yes on your second question. I don't have a clue on your first.

    As far as I know, you can't disable the USB power. Instead, why don't you wire the fan to the 5 volt rail of your computer's power supply?

    you cannot disable a USB fan. Why did you not use a fan power input from the mobo?
