    take me to school

    my case fan is acting up. how does work?
    2 sets of wires. 1 is the molex power, for poiwer. the second is the 3 pin for fan speed right. last night the fan was slowing up and speeding up asa if it was connected to the motherboard thermos. but it is not connected to the motherboard. only the power and speed knob. is the fan malfunctioning?

    Yes, malfunction in the junction.

    That's a fairly new system, isn't it? Or just new software?

    the 3 pin is power too, it just comes from the MB power and can be controlled.

    Hi DA,

    In other words, it's one or the other plug. Don't plug them both in.

    If you just want the fan to run at 100% all the time, use the 4 prong molex plug.

    If you want the motherboard to control the fan speed, find out what the 3 pin connector that you're plugging it into does.... or is named. Some are controllable and have specific names and others are just hot-wired like the 4 prong molex plugs. Look in the motherboard manual to find out what is what.
