A little expensive but it's very, very silent. Keeps my pc cool even though it doesn't feel like a lot of air is being pushed.

Super quiet. Get rid of the stickers. Very expensive.

Can't fault it. Noise is... well there's basically nothing, that's the thing. be quiet have done a fantastic job on this one.

Extremely quiet and well designed fans that are absolutely amazing at their job. Since I live in a dorm where I can't control the heating/cooling, the sound of the fans is usually overrun by the loud A/C unit in my apartment. However, even when the A/C is off, I barely hear a thing. These fans truly live up to their reputation of silence.

silent even at full speed and looks nice.

Quietest fans ever. Doesn't seem to push truckloads of air, but they work.

Quiet, and belt quite a good amount of air. Great for case/rad fans. Bit on the expensive side but they're black and the quality shows when you take them out of the box. Mounting is a breeze in either format as well.

Picked up a couple of these fans on a friend's recommendation since the fans that came included with the Fractal case I bought aren't PWM. Solid construction and whisper quiet.

SILENT! ;)

Sleek-looking, very quiet PWM fans that matched the aesthetics of my build. Very happy with them so far.
