The struggle is real you guys! I didn't realise how loud those pesky case fans can get until I put my case on top of the table, right next to me. I have the spec-04 tempered glass case, and the fan it came with is actually very decent. The real problem is the CM silent fan 120 SI2 that I have installed as the rear exhaust. It blows! and not literally. I don't have the specs(?) for the pre-installed corsair fan, but the CM is: 44.73 CFM 1.65 mm H2O 19.1 dB-A 1200 R.P.M DC voltage control So I guess what I am looking for is a fan that exceeds this in at least the top 3 specs(flow, pressure, and noise), and I would prefer PWM and red LEDs. I am not sure how much good fans cost, but the absolute max I am willing to spend is 3k for a pair, the lower the better of course. Any recommendations? Thanks!
