Noctua NF-S12A PWM Quiet PC Fan 120mm
The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations
from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic
Optimization) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The FLX version provides 1200/900/700rpm
speed settings via the supplied Low-Noise Adapters 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 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling..

Noctua NF-S12A PWM Features
Award-winning S12 design
The NF-S12A features the third evolution of Noctua’s classic Straight Blade Design that has earned its S12 series countless recommendations from hardware
journalists and enthusiasts around the world. Further optimized for even better airflow/noise efficiency, it makes the NF-S12A an ideal quiet case fan.
The NF-S12A’s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan’s stall margin. This
means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
Noctua’s AAO (Advanced Acoustic Optimization) 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 Design
Noctua’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 Microstructures
With the tips of the fan blades plowing 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 and improved airflow and pressure efficiency.
Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimize the transmission of minute vibrations while maintaining full compatibility with all standard
screws and other mounting systems.
Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-S12A PWM uses Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation
Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
The NF-S12A PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces the maximum fan speed from 1200 to 900rpm. The L.N.A can be used either to run
the fan at a fixed speed of 900rpm or to cap the maximum speed when using automatic PWM control.
Extensive Cabling Options
The fan’s short 20cm primary cable minimizes cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary.
Both cables are fully sleeved.
The NF-S12A features the further optimized second generation of Noctua’s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to
the axis to provide even better stabilization, precision and durability.
Metal bearing shell
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-S12A sports a CNC
milled bearing shell made entirely from brass.
6 years manufacturer’s warranty
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-S12A features an MTBF rating of more than
150.000 hours and comes with a full 6 years manufacturer’s warranty.
