There is a split on bearing type as well, Fluid Dynamic on the Scythe Kaze Flex II 120 PWM versus Sleeve on the SilverStone FN121. There is a split on connector type as well, 4-Pin PWM on the Scythe Kaze Flex II 120 PWM versus 3-Pin DC on the SilverStone FN121. Pwm control is not the same on both, Yes on the Scythe Kaze Flex II 120 PWM versus No on the SilverStone FN121. Positioning is not the same on both, Mainstream on the Scythe Kaze Flex II 120 PWM versus Budget on the SilverStone FN121.
Who each one is for
The Scythe Kaze Flex II 120 PWM is the one to take for quiet mainstream case airflow and Non-RGB builds, though it is not built for high static pressure radiator duty and show-window RGB builds. The SilverStone FN121 suits budget case airflow and quiet everyday builds, though it is not the pick for radiator or heatsink duty and RGB builds. Our rating of the Scythe Kaze Flex II 120 PWM (7/10): A dependable, quiet mainstream fan with nothing flashy about it, which is exactly the point. Our rating of the SilverStone FN121 (6/10): an unremarkable but reliably quiet budget fan for general case airflow.
Where the two are identical
The common ground is wider than the gap: fan size, lighting and max speed are identical here.
