Cooler Master SickleFlow 120 Review

The Cooler Master SickleFlow 120 is a non-RGB 120mm case fan with a rifle bearing, PWM control, 62 CFM airflow, 1800 RPM maximum speed and 27 dBA noise.

A simple budget fan with no lighting. The 4-pin PWM connector lets the board vary speed between 650 RPM and 1800 RPM, and the quiet speed noise level is listed as 8 dBA against 27 dBA at full speed. Airflow is 62 CFM. The fan is 25 mm thick, weighs 156 g and has a rated life of 160000 hours with a 2 year warranty. It comes in black, white or red. It is a sensible pick for filling several mounts cheaply.

A Budget Staple

The SickleFlow's signature loop-shaped blade design has been a fixture of budget PC builds for years, offering respectable airflow and static pressure for the price even without the ARGB version's lighting.

Comparison to Alternatives

Against the Cooler Master SickleFlow 120 ARGB already in this catalog, this non-RGB version performs identically and costs less, so skip the RGB model entirely if the case has a solid panel. Against the Arctic F12 PWM in the catalog, the SickleFlow pushes more static pressure at a similar price, making it the better pick behind a dust filter.
