Scythe Kaze Flex II 120 PWM Review

Scythe Kaze Flex II 120 PWM is a 120 mm, 26 mm thick, 4-pin PWM case fan with a fluid dynamic bearing, 300 to 1200 RPM speed range and a 120000 hour rated life, with no RGB.

The Kaze Flex II 120 is a mainstream 120 mm fan without lighting. It has a fluid dynamic bearing, 4-pin PWM control, a speed range of 300 to 1200 RPM and a 120000 hour rated life. At 26 mm thick it is slightly thicker than a standard 25 mm fan, so check space beside radiators or tight mounts.

Comparison to Alternatives

Against the be quiet! Shadow Wings 2 120mm PWM already in our catalog, the Kaze Flex II delivers similar airflow at a slightly lower noise level, both aimed at the same quiet-mainstream buyer. Compared with the Fractal Design Dynamic X2 GP-12, the Kaze Flex II is a close match on both airflow and noise, so brand preference and price will decide between them.
