    Default 40 mm Computer fans

    Hi Guys,
    I have a old 40mm fan which makes a lot of noise when running and going to replace it. The old fan is only two wires red and black. The new fan which I got from the computer shop which they ordered in has 3 wires red, black, yellow. If I connect up the red and black wires as the same as the old fan will the new fan still work or do I have to wire up the yellow as well.

    Thanks John.

    This may help Red and black should be enough. Red is 12v black is ground. yellow will be RPM which you cant use anyway

    Yeah just use red\black the same for power. Yellow wire will be RPM readout - you can connect it to a sensor on your motherboard if you have one, otherwise just ignore it.
    Non-system disk or disk error. Replace and strike any key when ready.
