A:Answer It comes with 3 RGB fans that can be controlled by iCue software you can download from Corsair. The back does not have a fan. When I built mine I used the H60 liquid cooled radiator. It fit perfect! I went radiator/fan/case that way I would not introduce any heat to the inside of the case. It works great. When I tried to put exhaust fans at the top of the case, they interfered with the RAM so I left them off. I also took the front cover off, light sanded and spray painted it with Krylon Fusion "Red Pepper" and then put a gloss clear coat over that. Looks great, has a splash of color and easy to do.
