I have the enthoo pro m that came came with the rgb halos fans on the front. these 4 unlabeled cords were in the back, and thats where they go. I figured out one was a sata cable, but no idea what the rest are. one says only plug into phanteks rgb strips. But when i turn my pc on, everything but these fans work. I thought of plugging it into Sys_Fan on the mobo, but the small one is too small, and the others are too big.
