    Max output of 3-pin power connectors

    What's the maximum typical allowable current draw from the 12v 3-pin fan headers on the motherboard, both individually, and for the whole lot of them?

    most older ones (over 1 year) should not be ran past 2-3w. Most newer ones can usually take 4-5w (or possibly more). I would not hook up a 120mm case fan to a 3 pin header, but a Delta 38 is fine or most 80mm or even some low noise 92mm fans will stay around 3w.

    Darn; have a 120mm that draws 5.64W. It also has a tachometer which I would have liked to use, and I can't really afford to get one of those stand-alone system monitoring add-ins. Oh well; thanks anyway.
