I have the Rosewill blackhawk case and the ASUS P8Z77-V LK motherboard. The case came with 5 fans, and the motherboard only supports 3 fan plug ins. Should I connect the other two directly to the PSU, leave them unplugged, or is their an adapter to plug two fans into one of the ports on the motherboard? Should I just get a fan controller and plug all 5 in? Also, if I only plug 3 fans into the motherboard, which 3 should I plug in? There are 2 in front, one on top, one in back, and one on the side of the case. Any advice would be much appreciated.
