    Maybe try turning off the computer, even though it means that you will be away from bit-tech for a minute or two.

    How about turning the computer off, mounting the fan bus, and turning the computer on again?

    Then you'll have to look for places where the + wires can be touching a ground wire or the computer chassis.

    how many switches have you got?

    which terminal of the switch is connected to the switch housing?

    This terminal needs to be gnd and the outher your 12V/7V/5V

    Make sure all the switches are wired the same

    if the switch is of the "metal arm" type... (or whatever you call it) the center connection is often (specially on the cheap ones) in contact with the arm itself... this is becase the arm is metal.. and it as a little tap that just slides over the "contact plate".. (hard to explain.. but believe me.. i have taken o few apart... :dremel: )

    if the switches is in contact with th positive (as i assume it it because it probably switches between 12 and 5 volts or something) then the whole matel boty of the swich becomes connected to positive... negative is often on the case... with the plastic front you are ok cus' this insulates.. but with a metal fron you make a connection...

    The PCmods ones shouldn't short unless you plugged all six fly leads in and not into six fans? Like ours the 3 pin male KK connectors are live and can short on case.

    Is it possible that somewhere a live wire is touching your case and when you put it in, it completes the circuit?

    Yes - thats what I was getting at but eliminating the possibilty of the live flyleads being a problem..

    would take a look for a minimal charge as a hexus user?
