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 blue 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 1 out of 5 by from Quiet as a small jet during take-off I fitted 2 of these to a new Thermaltake case believing I would need them to vent sufficient air for my recently upgraded graphics card. I couldn't believe my ears when the system wooshed into action. I tested them every which way thinking I had done something wrong, but no, I hadn't. What a total waste of money not to mention a fraudulent description to label them "quiet". I subsequently ripped the case fan from my old box before binning it and connected it instead. I now run 2 supposedly "rubbish" cheapo case fans nearly silently and without straining the air supply to my system while the expensive Cooler Masters sit disconnected and in silent darkness on the front. If anyone wants to take them off my hands they're free to a good home.
