Noctua NF-A14 PWM 115.5 - 140.2 m3/h | 19.2 - 24.6 dBA Phanteks PH-F140SP 82.1 CFM | 19 dBA Fractal Design Venturi HF-14 118.2 CFM | 26.5 dBA I plan on getting a Corsair Air 540, and need to get some fans to go with it. Either two fans to supplement the Corsair AF140's that come with it, or if I really decide it's worth it, three additional ones to replace those as well. Trying to find something that (hopefully) balances budget but pushes a lot of air (still, none of the ones I'm looking at are particularly all that cheap). It doesn't have to be super obsessed with being quiet, but nothing super loud. I was thinking at least under 30 dB, maybe even 25. I've never been too bothered by a bit of noise as long as it's nothing out of the ordinary like squeaking, coil whine, etc. The Phanteks and Fractal Design peaked my interest because of their manufacturer's (supposed) ratings, and Noctua because of their reputation. Is there anything else I should be looking at? Anything else besides the Venturi in the $15 and under range if I decide to go with 5 fans? Some of these manufacturers have so many models of 140mm fans that it's difficult to look at and compare them all. Thanks!
