    I taken a fan out of a dell pc and it looks very fast, if i remember it wasnt noisy either.

    most 120mm fans are 25mm wide, but this one os about 40mm.

    My question is - I want to run this from a molex and it comes with 4 wires. Which wires do I use.

    the colours are - blue-red-white-black

    many thanks if you can help.

    Normally;

    Black - Negative ground
    Red - Positive volts
    Blue - Speed monitor(rpm)
    White - Speed variable control

    But hey, it's dell so just stick with the red and black.:toast:
