Hi guys, I was wondering what these 3 cables that come from the case(near the optical drive) are. One has four pins, the other two have two pins. Here are some pictures: http://imgur.com/BGLz2qa. Thanks!
 


Yes my bad, I meant the R4. So do I need to connect the fan controller power connector to the mobo or is it just optional?
 


My R4 manual is pretty bad, all it shows is an exploded view with labelled parts, none of the cables are mentioned :l
 


Wow thank you so much! I was wondering why my case fan couldn't reach my mobo. I appreciate all the help :)
