Product features
Anti-stall knobs
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.AAO frame
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.PWM 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.Key selling points
