Noctua NF-F12PWM Computer case Fan 12 cm Brown

Focused Flow FrameDesigned for pressure demanding applications such as heatsinks and radiators, the Focused Flow 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. buttonVarying Angular Distance and Vortex Control NotchesThe 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. buttonHeptaperf Heptaperf ImpellerCustom designed for the new Focused Flow frame and to work in tandem with the eleven stator guide vanes, the NF-F12 s seven blade Heptaperf impeller has been carefully optimised to achieve a perfect balance between power and quietness.Stepped Inlet DesignNoctua 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. buttonInner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. buttonIntegrated Anti-Vibration PadsIntegrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks.
