How much air does this fan move and is it loud?
If you’re looking for a fan that provides fantastic airflow around your system, whilst producing little noise, then this Cooler Master SickleFlow fan would be great for you. The fan blades on this are sickle-shaped and curved, and when spun at 2000RPM generates a high airflow of 69.9CFM – helping to keep your computer system cool. Four red LEDs are used to provide a terrific visual effect, which is emphasised with the light brown clear fan blades. Producing 19dBA of noise makes this fan quiet, so as to not disturb you while gaming.

Where should I place these fans?
This fan can be used for almost all applications, with it being able to transport up to 69.69CFM of air and creating up to 2.94mm/H20 pressure. The high airflow produced by this fan makes it great for use in an open location, where not a lot is blocking the fan. Additionally, with a static pressure of 2.94mm/H2O this fan is excellent for use in tight spaces where there may be driver bays or a radiator blocking the fan.

Rated 5 out of 5 by from Excellent value for low noise cooling I bought 4 of these to fit out the optional fan mounts in my Cooler Master Storm Trooper case. They are very good value for money and excellent in terms of noise and performance. I have them hooked up to the Top Panel Fan controller which allows you to set the fan speeds from a range of 1 to 6. These things run almost silent on low (1) and aren't much louder on mid and high settings. Excellent and the RED LED look is a nice touch. They only have a standard 3 pin fan connection - there is no LED on/off cable with these fans.

Rated 2 out of 5 by from its quiet i bought one of these because i was drawn to that red glow that you see in the picture, but really the led is horrendous, its dim,dull and really you wouldnt even notice it, i was quite disappointed with it. Because of this i will probably return it.

Rated 1 out of 5 by from Awful Bought this mainly on brand and expected it to do what it says. It didn't. Imagine flying in an aircraft without an soundproofing.
