I have a new XSPC pump/res combo that came with two D5 pumps. The pumps have a 2 pin molex, but also a 3pin fan header with just one wire running into it. I would guess this would be to control the speed of the pump but it already has a manual speed setting on it. Do I need to plug in the 3pin connector or can I just use the molex only?
