SilverStone FN121 (120mm/44.5 CFM/1.1 mmH2O Static Pressure/1500 RPM Max/20.0 dBA/Rifle Bearing/No RGB/PWM) Review

The FN121 is SilverStone's plain everyday case fan, the one to search for when you just need a cheap, quiet 120mm replacement with no lighting.

It won't win any airflow contests, but it's quiet enough to forget it's there in a standard mid-tower.

Comparison to Alternatives

Against the be quiet! Pure Wings 3 120mm PWM already in our catalog, the FN121 is quieter at idle but gives up several CFM of airflow, a fair trade for a budget-focused build. Compared with the SilverStone FQ121 above, the FN121 skips the static-pressure-tuned blade design for lower cost and a plainer, quieter general-purpose fan.
