Neoseeker posted a review on the Noctua NF-F12 PWM 120mm Cooling Fan
Noctua's latest offering in their cooling lineup, the NF-F12 120MM case fan, is designed specifically for use on heatsinks and radiators Priced around $30, the NF-F12 is packed with all new features and capabilities like 11 stator vanes, which come as part of the fan's new Focused Flow Frame. These vanes have been designed specifically to straighten, channel and focus airflow, thus increasing the cooling performance of the fan.Noctua NF-F12 PWM 120mm Cooling Fan Review
The new Frame design is coupled with Noctua's radical new Stepped Inlet technology. The main function of the Stepped Inlet design is to force the airflow from laminar to turbulent airflow in the fan's influx, increasing overall airflow efficiency. Paired with a 7 blade design, the enhanced Focused Flow Frame significantly increases the fans static pressure.
Another new feature is the second generation SSO2 bearing. With this new design, the rear bearing has been moved closer to the axis providing more efficient stabilization along with added precision and increased durability.
