Okay so on my 922HAF cooler master I have three case fans, one top, one back and one front. The fans came with a three pin connector attach to a four pin male/female power cable. My power supply has a cable that has three male 4 pin connectors that fit those so I plugged all three fans into that cable. Towards the end of the cable there is also a small four pin connector that looks like it is meant to go into the motherboard. Should I leave the fans connected to this cable and also plug that small four pin connector into the motherboard chassis/fan header? What is the best way to set this up?
