    That information is from 2009.
    The question today is if the 3 amp safe maximum applies to newer boards' fan headers also.

    My preference is to buy a quality fan controller with high enough capacity for each fan channel to safely handle two or more fans per channel, where each fan's maximum draw is about 1/2 amp (6 watts) or less. This way I can control the individual fan speeds, noise and cooling depending on ambient temperatures and system loads.

    I'm sure it does still apply, although it could be higher now but I doubt it.

    If you want to know for sure submit a question to GTTS and they'll let you know. I agree, fan controller is better than using the board anyway!

    What manual do you see that in?

    Like I said above, I guess someone really needs to ask GTTS to see if that info is still up to date.

    Can't find that info now, I think someone else on another forum also asked about cpu fan header from Gigabyte and they said 1 A max.

    FWIW, I don't recall seeing fan header electrical specs in any of the Gigabyte motherboard manuals that I've read.
    I frequently look at motherboard user manuals when forum members post questions.

    Ya, that's why I asked which manual, because I've never seen it either in any Gigabyte manual

    Someone please ask here, I'm a little too busy to ask right now, then we wait

    If someone reports back, be sure to include the motherboard model name that you inquired about.

    Yes, you should disconnect a green wires that goes to one of the male connectors.
    Yeah, that didn't work either. The readout was always toggling back and forth like it's looking at 2 fans. So I clipped all but the power and ground from one male, but the fans seem to be running almost wide open. I'm confused again.

    OK I was wrong. I did clip all but the voltage wires from one leg of the Y connected to the female.
    So I should clip a green wire only from one of the males, correct?
