Hi, I'm halfway finished builing my PC, bying the components when I can. My Antec 1200 has now got power from my Corsair AX860 and the mobo, asus maximus vii hero seems to work fine, but when I power up the system, only the CPU fan and one other fan works. The one besides the CPU fan is whichever I plug into the "CPU_OPT". All the others which are plugged into "CHAN_FANx" won't blow/suck air. How do I make them do so?
