The NF-S12A marks the third generation of silent box fans of the iconic Noctua S12 series that has received more than 250 awards and international press recommendations. It has an improved blade design with Anti-Stall Knobs complemented by the new Advanced Acoustic Optimization AAO framework that makes the NF-S12A improve the noise air flow rate compared to to that of its acclaimed predecessor by up to 8%. The FLX version is capable of adjusting the speed of 1200/900/700 RPM through the included noise reduction adapters to offer complete flexibility in its adjustment to optimize fan performance to the maximum at close to absolute silence operation. Thanks to its magnificent smooth operation,
Award -winning design S12 The NF-S12A has the third version of the evolution of the classic design of straight blades of Noctua that has achieved innumerable recommendations of journalists specialized in hardware and enthusiasts around the world. Improved airflow efficiency that makes the NF-S12A an ideal case fan.
Anti-Stall Knobs The NF-S12A's Anti-Stall Knobs reduce the phenomenon of flow separation in medium and high impedance situations thereby increasing the fan's stagnation range. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance in heatsinks and radiators.
AAO frame The frames with Advanced Acoustic Optimization AAO (Advanced Acoustic Optimization) of Noctua have integrated anti-vibration panels in addition to technologies such as Stepped Inlet Design and Inner Surface Microstructures that improve the efficiency of the fan.
Stepped Inlet Design Noctua's Stepped Inlet Design adds turbulence to the inflow to facilitate the transition from laminar flow to turbulent flow, which reduces noise, improves adhesion of the flow and increase the suction capacity, especially in confined space environments.
Inner Surface Microstructures (Internal Surface Microstructures) When the tips of the fan blades pass through the Inner Surface Microstructures, the separation of the flow with respect to the suction side of the blades is significantly suppressed, reducing blade rotation noise and improving air flow and pressure efficiency .
Integrated Anti-Vibration Pads (Integrated Anti-Vibration Panels) Integrated Anti-Vibration Panels made of extra soft silicone that minimize the transmission of small vibrations while maintaining complete compatibility with all standard screws and other mounting systems.
Smooth Commutation Drive 2 (Soft Switching Unit 2) The latest version of the advanced Smooth Commutation Drive system from Noctua guarantees excellent smooth operation as it eliminates noise in PWM changes. That is why the NF-S12A is extraordinarily silent even at the smallest distances.
3 speed settings for complete flexibility By providing 1200, 900 and 700 RPM speed settings through the Low-Noise and Ultra-Low-Noise adapters, the NF-S12A FLX can be adjusted for superior air flow or a maximum silence
Extensible Wiring Options The 20 cm main fan cable minimizes cable build-up, while the included 30 cm extension cable provides greater reach when necessary. Both cables are completely meshed.
SSO2 bearings The combination of the efficient hydrodynamic bearing concept with an additional magnet makes Noctua SSO-Bearing technology synonymous with extremely quiet operation and exceptional long-term stability.
