Noctua NF-S12A PWM 120x120x25

The NF-S12A marks the third generation of silent case fans in Noctua's iconic S12 series that has received more than 250 awards and international press recommendations. Featuring an improved blade design with Anti-Stall Knobs complemented by the new AAO (Advanced Acoustic Optimization) frame, the NF-S12A improves noise airflow ratio over that of its acclaimed predecessor by up to 8%. The PWM modulator version uses the Noctua-designed NE-FD1 IC for fully automatic speed control via a 4-pin connector and comes with a noise reduction adapter to lower the maximum speed during PWM modulator control. from 1200 to 900 rpm. Thanks to its magnificent smoothness in its operation, the SSO2 bearing and the renowned Noctua quality make it a first-rate option in silent case dissipation.

The NF-S12A features the third version of the evolution of Noctua's classic Straight Blade Design that has earned countless recommendations from hardware journalists and enthusiasts around the world for its S12 series. Better optimized for even better noise airflow efficiency, making the NF-S12A an ideal quiet case fan.

Those of the NF-S12A reduce the phenomenon of flow separation in situations of medium and high impedance, therefore increasing the fan's stagnation margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance in heatsinks and radiators.

Noctua's AAO (Advanced Acoustic Optimization) frames feature built-in anti-vibration pads, as well as step-in input design and internal surface microstructures (both proprietary to Noctua), which further refine sonic efficiency and performance. fan performance.

Noctua's step-through inlet design adds turbulence to the air inlet to facilitate the transition from laminar flow to turbulent flow, reducing inlet pitch noise, improving flow adhesion, and increasing suction capacity, especially in environments with restricted space.

With the ends of the fan blades colliding with the boundary layer created by the Inner Surface Microstructures, the flow separation from the suction side of the blades decreases significantly, resulting in noise. smaller pitch between the blades, better air flow and greater pressure efficiency.

Integrated anti-vibration pads made of extra-soft silicone minimize the transmission of vibrations per minute while maintaining compatibility with all standard mounting systems and fan clips used on coolers.
