3 fans one header on motherboard

RandeeWhite · Sep 6, 2014

I have a gigabyte ga 78lmt usb3 micro atx am3+ motherboard that has only 1 system fan header. My corsair c70 case has 3 fans. How can I get the other 2 fans going? My PSU is a corsair cx750w.

Thanks for the help. Just ordered molex to 3 pin adapter. Thanks again.

Most fans have two ways to plug them in, either to the motherboard or directly to the PSU. There should be a larger male 4-pin cable that can plug from the PSU into the female 4-pin cable coming from the fan. Fans connected to the PSU directly always run at 100%.

You need to plug the other fans into the power supply using moles to 4-pin or 3-pin adapters. Plugging 3 fans into one motherboard header is a bad idea as it will overload the header.

You could have them plugged directly into the PSU as stated above, or you could get a fan controller to put all of the fans on. You could also use two splitters to give yourself the three connections that you need. Just be careful though as you can overload the fan header.
