I have one of those coolermaster high air flow cases that has 6 places to put 120mm fans, but my motherboard only has 4 case fan headers. So I'm thinking about using a 200mm fan in the front intake and another in the top exhaust. I was wondering if anyone has a 200mm fan that moves a good amount of air, because my CM megaflow that I have as the top exhaust on high speed moves as much air as a 120mm fan spinning at low-medium speed. I could buy a fan controller and just use all 120mm fans, but that would cost more than 2 big fans, and wouldn't be as quiet either. Anyone got any ideas?
