CPU fan error...but fan is spinning

By kobe_forever

  1. hi! just assembled Asus P5RD1-V MoBo with Intel Pentium D 805 DualCore! the original intel fan (4pin) made too much noise so i got Speeze Intel P4 775 cooler (3pin) instead. i have set jumpers accordingly for 3pin fan....and the fan is spinning nice and quietly but during startup i experience a "fan error" message. cpu temperature is in normal parameters also (around 40^C). any ideas of what the problem might be?
    thanks in advance

    hi kobe and welcome to techspot :)

    have you updated the BIOS? a newer version may fix it if the problem is a "false error"

    though normally you don't need to move any jumpers to use a 3 pin fan on a 4 pin header. just plug it in like this:
    try setting the jumper back to the "4 pin" setting and see if the error goes away. if the fan spins, then i wouldn't worry about the jumper setting.

    that depends.

    in the past you had to update the BIOS in DOS mode via a floppy disk

    but now days you can update almost all BIOSes from a windows based program.

    your motherboard's support CD will usually include a BIOS update program or you can goto the momo maker's website and view instructions there.

    but before you do that, try the simple hardware setting that I mentioned before, because a power loss during a BIOS update will make your mobo into a paperweight ;)

    Some FANS only have 2 leads as opposed to 3.
    If there are only 2 leads then the motherboard will not pick up the fan

    kobe doesn't has a 3pin fan, not a 2pin fan.

    (it's in the 1rst post :))
