Hey guys, Helping roommate finish up his build, but we can't get the RGB working on the fans and I believe its due to a cable coming off the hub.

It's the cable in the picture from this guys post. We do not have an Add RGB Header on Mobo so is there somewhere else we should be plugging this cable into....
