TECHNICAL DATA:

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. Since it has an improved blade design with  Anti-Stall Knobs  complemented by the new AAO frame   designed by Noctua for fully automatic speed control through a 4-pin connector and comes with an adapter noise reduction to decrease the maximum speed during the control of the PWM modulator from 1200 to 900 rpm. Thanks to its superb smooth operation, the SSO2 bearing  and the renowned Noctua quality make it a first-order option in silent case dissipation.   (Advanced Acoustic Optimization) , the NF-S12A improves the airflow rate for noise compared to its acclaimed predecessor by up to 8%. The PWM modulator version uses the NE-FD1 integrated circuit 

The 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 from all over the world for its S12 series. Better optimized for even better noise airflow efficiency, making the NF-S12A an ideal silent box fan.

Anti-Stall Knobs

The Anti-Stall Knobs of the NF-S12A reduce the phenomenon of flow separation in situations of medium and high impedance 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 proprietary Noctua technologies such as Stepped Inlet Design and Inner Surface Microstructures that improve the efficiency of performance by fan noise.

Stepped Inlet Design

The Stepped Inlet Design of Noctua adds turbulence to the inflow to facilitate the transition from laminar flow to turbulent flow, which reduces the tonal input noise, improves the adhesion of the flow and increases the flow suction capacity, especially in confined space environments.

Inner Surface Microstructures (Internal Surface Microstructures)

When the tips of the fan blades pass through the delimiter layer created by the Inner Surface Microstructures, the separation of the flow with respect to the suction side of the blades is significantly suppressed, reducing the blade rotation noise and improving the air flow and pressure efficiency. 

Integrated Anti-Vibration Pads

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.

PWM IC of own design with SCD (Soft Switching Unit)

With full support for automatic PWM speed control, the NF-S12A PWM uses the new Noctua-designed NE-FD1 PWM IC that integrates with Smooth Commutation Drive (SCD, Soft Switching Unit) technology. By providing smoother torque pulses, the SCD decreases the noise of PWM shifts and makes the fan run quieter at low speeds.

Extensible Wiring Options

The 20cm main short cable of the fan minimizes the cable mess in typical situations while the supplied 30cm extension cable allows extra reach when necessary. Both cables are fully lined.

SSO2 bearings

The NF-S12A has the recognized Noctua second generation SSO optimized bearings. With SSO2, the rear magnet is located closer to the shaft to provide greater stability, precision and durability.

Metal bearing

In order to guarantee the highest possible degree of precision in its manufacture, a minimum tolerance and excellent long-term stability, the NF-S12A uses a CNC-milled bearing made entirely of brass
