My case has two fans. One is on top, which draws its power from the front panel. It works fine. The other is on the side and needs to be plugged into the motherboard. It has a 2-pin connector My motherboard is a GA-F2A88X-D3H. It has, as far as I can tell, three fan headers. One is 3-pin, the other two are 4-pin. See picture. http://s9.postimg.org/i816h55dr/8747_big.jpg Where do I connect my 2-pin fan?
