Scythe Kaze Flex II 120 PWM (120mm/43.71 CFM/1.33 mmH2O Static Pressure/1200 RPM Max/21.8 dBA/Fluid Dynamic Bearing/No RGB/PWM) Review

The Kaze Flex II is Scythe's updated version of a long-running budget-to-mid fan line, so people search for it comparing generation two against the original Kaze Flex.

It's a quiet, unremarkable fan in the best way, a safe pick for anyone who just wants reliable Japanese-engineered airflow without lighting.

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.
