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.
The NF-S12A's Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations n thereby increase the fan's stall margin, that is even more versatile than its renowned predecessor .
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.
Noctua's Stepped Inlet Design adds turbulence to the influx to facilitate the transition for laminar flow to turbulent flow, that reduces tonal intake noise, improves flow attachment, incur suction capacity, especially in space restricted environments.
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.
The latest version of Noctua's advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-S12A remarkably quiet even at very close distance.
Providing 1200, 900 and 700 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-S12A FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.
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.
