Noctua NF-F12 5V Premium, 120mm -tuuletin

The NF-F12 5V is a dedicated 5V version of Noctua’s award-winning, premium-quality NF-F12 120mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures such as the FocusedFlow™ system, the NF-F12 is renowned for its superior performance and outstanding quietness of operation. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing guarantee superb running smoothness and excellent long-term stability. Topped off with the included USB power adaptor cable, OmniJoin™ adaptor set and 6-year manufacturer’s warranty, the NF-F12 5V is a premium choice for demanding 5V applications.Being a 5V fan, the NF-F12 5V cannot be run at 12V and will be damaged when used with typical 12V power sources such as PC motherboard fan headers.Award-winning NF-F12 designHaving received more than 100 awards and recommendations from the international press, Noctua's NF-F12 has become a proven premium choice for 120mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.5V version5V fans are used in various devices and applications. With the included USB power adaptor cable and OmniJoin™ adaptor set, the NF-F12 5V is a proven premium solution that gives you full flexibility both for replacing existing 5V fans and for new, custom applications.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.Varying 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.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.AAO frameNoctua's AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.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.Inner 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... ...
