So basically, this (CM Megaflow; 200mm) or this (BitFenix Spectre Pro; 230mm)? The CM one is a quieter, so I'm leaning towards that; however, it lacks PWM control, so I was thinking I could just get the Spectre and then control it to make it quieter than the CM Megaflow if needed. The fan would be used for intake at the front of a BitFenix Prodigy (black). Thanks!
