Noctua NF F12 PWM 120mm Focused Flow PWM Cooling Fan

Teaming up eleven stator guide vanes with a specially conceived seven blade impeller, the NF F12's Focused Flowâ„¢ system creates outstanding static pressure and focuses the airflow for superior performance on heatsinks and radiators. At the same time, a wide range of advanced aerodynamic design measures, second generation SSO Bearings and Noctua's new, custom designed PWM IC for fully automatic control guarantee astounding quietness of operation. The NF F12 comes with modular cabling, integrated anti vibration pads and two speed settings for full flexibility. Its commanding performance, exhaustive set of features and Noctua's trusted premium quality make it an elite choice for use on air coolers, radiators and other pressure demanding applications. **Focused Flow Frame** Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flowâ„¢ frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF F12 to rival the performance of conventional fans running at much faster speeds. **Varying Angular Distance and Vortex Control Notches** The NF F12's stator guide vanes are set out in Varying Angular Distance and feature Vortex Control Notches. Both measures help to spread the noise emission over a broader frequency spectrum and thus make the fan's sound pattern more agreeable to the human ear. **Heptaperfâ„¢ Impeller** Custom designed for the new Focused Flowâ„¢ frame and to work in tandem with the eleven stator guide vanes, the NF F12's seven blade Heptaperfâ„¢ impeller has been carefully optimised to achieve a perfect balance between power and quietness. **Stepped Inlet Design** Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space restricted environments. **Inner Surface Microst
