i saw the post about what fans that guy suggested but those were not variable speed. im modding my case to fit 2 120mm fans, one on the front blowing up and one blowin onto the cpu via a duct. anyways i need some fans that push alot of air when at full speed, but that i can turn down when word processing or somethin like that. can you guys give me some good suggestions for fans? an alternate idea, can i just get a fan controller and get normal fans or must my fans be variable for the controller to work?
