Great big -quiet- fanFeb 26, 2010
the fan does very well for itself. it blows!
I use it as a second fan for my Corsair H50 and it works great
Great quiet fan the equipment it is in isn't well designedOct 29, 2009
This fan is very quiet. It replaced a high end Pabst fan with less CFM. The case I placed the fan in creates a bit of wind noise as the air is pulled in. Non restricted flow is critical to getting the most from a high quality fan with lowest circulation noise. I used this one without the speed control yellow wire.
The difference between this fan and the Pabst it replaced besides the airflow... when you manually turn the fan, there is not noticeable feel as with the Pabst. Sooo very smooth.

High Quality FanMay 01, 2009
First of all, Scythe has 4 models of S-Flex fans, SFF21D, SFF21E, SFF21F, SFF21G, with increasing RPMs and of course noise levels. I have SFF21E and SFF21F, one in front as intake and another in the back as exhaust. Both fans are high quality and run very quietly. The back one runs at ~1000 RPM due to the speed control on my motherboard but it still generates quite a bit of air flow. I'm very happy with this product.

Super quiet. Moves a lot of airFeb 28, 2008
I use a pair of these to move air through my audio/video receiver and cable company DVR. They are in a cabinet with a glass door and I was worried about heat build-up. I had already drilled some large holes in the back (top and bottom) of the cabinet and in the shelf under the two devices. I placed one fan above each device and the air is pulled through. I used the switched plug on the back of each device to turn the fans on. I wired them up using some 12VDC power supplies from defunct electronics.
Just ignore the yellow wire coming from the fan. That is used for feedback of the speed if you are controlling them with a thermostat. Just hook up the red and black wires.
Very slient. Can't hear anything outside the cabinet when they are on.
Silent as a whisper...Jul 20, 2007
As the title says, this 120 mm cooler makes absolutely no noise at all, it works with a speed of 1200 rpm and cools very well. I paired it with a thermalright ultra 120, first sight love, sweet!!!..
