Got it from a thrift shop for this price, and am very satisfied! Cool and moves a lot of air! My only issue with it is that the wire BARELY made it to the mobo. I had to reorient it several times and it still is almost stretching. Not sure whether to blame it on this, the mobo, or the case, however

Silent! Good for situations where static pressure is needed!

600 -1300 RPM | 2.76 mm H2O | 89.55 CFM | 12.5 -22.19 dB

Works great as intake for my case, since the room for intake is very closed or has not much space. Would work great for radiators too.

I was skeptical about these fans at first because they aren't super popular but they are very nice. They push a good amount of air and are very quiet and low rpms. They are PWM too.

Working great for me. nice and quiet. blows air.

Great price-performance ratio, but they produce an audible PWM ticking noise that is hard to ignore at low RPMs.

Quite good for the price to cfm to loudness ratio

Pretty quiet yet seems to move a lot of air. Sleeved cables are nice. The rubber things to install them look a bit odd, but hey, it works.

Nice 140's. Well-made and pretty quiet (can hardly hear them at normal speeds).

This fan surprised the hell out of me. I didn't think an $11.99 fan would work this well. But I am happily surprised. It is fairly quiet, with a headset on you won't notice anyway, so who cares! Comes with rubber screws (if that is what you call the rubber things you pull through) which took me a while to figure out but once I got it they are super convenient and I wish my other fans had them.
