    Fan Header Problem

    Ive just got myself a 40mm chipset fan and its worked fine when I plugged it into the chipset fan header on the mobo...as the wire was too long, I snipped and rewired the fan to have a shorter wire and this is when the problem arises...

    the fan refuses to work now...all it does is just jerk a little when I plug it into the already switched on mobo...weird problem is that the same fan works when I plugged it into the cpu fan header...and the cpu fan works fine in the chipset fan header tho was a lil slower...

    anyone knows whats wrong?

    Proably the wiring for the fan has been affected when you cut and rewired it back...check that that wires connection are tight...

    Erm...

    But remember that the same fan works on another fan header?

    Anyway Ive tried switching the wires but to no avail...

    Is it possible that Ive somehow blown the fan header when I plugged in the fan when the mobo was on?

    This is because when I plugged in another fan, its moved but was at an uncomfortably slow speed...like its leaking power or something...

    The chipset fan works when I plugged it into the molex plugs...

    Thanks for the reply...dint think anyone was gona reply...

    You could put a meter on the fan header pins, but be careful. The pins are very small and the meter probe tips are large. It's too easy to touch both pins and short them out. Now, how would I know this?
    If you have a fan plug with wire leads it would be safer to attach that and check the ends of the wires with the meter.
