Connect Two Case Fans To One Header

It usually works to connect two fans to one header with a splitter cable.

Connect two case fans to one header.

The easiest and cheapest option is to obtain a y splitter for the 2 fans and control them both with a single fan mate fan mate plugged into mother board then splitter going to the 2 fans. Second part will be about connecting up to 6 fans using same tools as in first case plus 4 pin molex cable and electric tape or shrinking tube or soldering iron tape. This then leaves the other single fan and header conection to the motherboard for control. There is only one caveat.

Although you could try connecting 2 fans to each header and not using one of the rpm wires they should be the same anyway and yes they will be controlled as if they were one fan. Basically the block you attach to the cpu has a pump installed this pump head is powered by connecting the sata capable and there s also what looks like a 3 pin female that appears to connect to a fan header the pump is also connected to your motherboard by an internal usb connection the pump head also has two places where you can. If the total current drawn by the two fans is less than that rating they can share the header but not if the total current exceeds 1 amp. If you want absolute control over your fans the best option would be a dedicated fan controller.

Each fan header is rated for up to 1 amp.
