Noctua NF-S12A FLX Ultra Quiet 120mm Flexible Cooling Fan The NF-S12S-FLX is a premium quality fan that offers full flexibility in quiet to ultra-quiet case cooling thanks to its Advanced Acoustic Optimisations. Features Noise levels from only 7.4 d B (A) High 63.27 CFM airflow Advanced Acoustic Optimisation Frame Three speed settings for maximum quietness Smooth SSO-Bearings Six year warranty Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO or Advanced Acoustic Optimisation frame. The NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The FLX version provides 1200 / 900 / 700 rpm speed settings via the supplied Low-Noise Adaptors in order to give you full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, SSO2-Bearings & Noctuas trusted premium quality make it an elite choice for quiet case cooling. Noctuas Advanced Acoustic Optimisation Frame Noctuas AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctuas proprietary Stepped Inlet Design & Inner Surface Microstructures, both of which further refine the fans performance/noise efficiency. Anti-stall Knobs: What is Stall? Noctuas S12 series fans impellers use a high angle of attack in order to achieve superior airflow. However, impellers with high angles of attack are typically more prone to undesired stall & flow separation phenomena that can occur when the fan is working against higher impedance such as when blowing through tight fan filters or when used on heatsinks & radiators. In these situations when the fan is building up high pressure but less air is moving through, the speed of the air particles flowing alongside the suction side of the fan blades gradually decreases towards the trailing edge. The lower the speed & the higher the counter-pressure, the higher the risk of the air particles becoming detached from the blade surface. This flow separation phenomenon known as stall leads to undesired turbulence, reduced efficiency & translates into a dent in the fans performance curve. Integrated Anti-Vibration Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws & other mounting systems. Smooth Commutation Drive 2 The latest version of Noctuas advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations & switching noises. This makes the NF-S12A remarkably quiet even at very close distance. Stepped Inlet Design Noctuas 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 & increases suction capacity, especially in space restricted environments. Inner Surface Microstructures With 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 & enhanced airflow & pressure efficiency. Package Contents As expected from Noctua, the fan is well packaged & is supplied with both the usual fan mounting screws & also rubber fan mounts to isolate the fan from the case ensuring that no vibrations from the fan can reach the case. Two in-line resistors are also included & these simply lower the voltage & therefore the speed of the fan if full speed isn't required. A Molex adapter allowing you to power the fan from the PSU & an extension cable are also included. Specifications Size

Stepped Inlet Design Noctuas 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 & increases suction capacity, especially in space restricted environments. Inner Surface Microstructures With 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 & enhanced airflow & pressure efficiency. Package Contents As expected from Noctua, the fan is well packaged & is supplied with both the usual fan mounting screws & also rubber fan mounts to isolate the fan from the case ensuring that no vibrations from the fan can reach the case. An in-line resistors (L.N.A) is included & this simply lowers the voltage & therefore the speed of the fan from 800 to 600 rpm if full speed isn't required. A Molex adapter allowing you to power the fan from the PSU & an extension cable are also included. Specifications: Size
