The NF-S12A housing fan marks the third generation of Noctua's classic S12 series, which has received more than 250 awards and recommendations in the international trade press. Thanks to the improved blade geometry with anti-stall knobs and the new AAO frame (short for Advanced Acoustic Optimization), the NF-S12A achieves up to 8% higher efficiency (delivery rate/noise development) compared to its renowned predecessor. With its super-slow speed options (800/600rpm), the ULN version enables almost silent operation and is therefore perfect for ultra-low noise applications and particularly noise-sensitive users. Its outstanding smoothness, the SSO2 reference class bearing and Noctua's proven premium quality make the NF-S12A a choice for noise-optimized housing cooling.
Award-winning S12 design
The NF-S12A uses the third evolution stage of Noctua's classic straight blade design, which has entered the S12 series with countless recommendations from hardware enthusiasts and journalists around the globe. Further optimized for even better airflow/noise efficiency, the NF-S12A is the ideal silent housing fan.
Anti-Stall Knobs
The NF-S12A reduces eddy-removal phenomena in situations with medium to high flow resistance and thus extends the so-called stall margin (current break limit). This makes the NF-S12A even more versatile than its predecessor and enables better results on heat sinks and radiators.
Integrated Anti-Vibration Pads
The anti-vibration pads, made from extra-soft silicone, reduce the transmission of minimal vibrations while being compatible with all standard mounting systems and fan clips used in CPU coolers.
Smooth Commutation Drive 2
The latest, further developed version of Noctua's SCD drive system guarantees outstanding smoothness by eliminating torque fluctuations and switching noises. This makes the NF-S12A surprisingly quiet even from close proximity.
2 speed options for maximum smoothness
The ULN (Ultra-Low-noise) version offers 800rpm and 600rpm settings via the supplied adapter, making it perfect for silent enthusiasts who demand super-slow speeds and minimum noise emission.
Comprehensive Connectivity Options
While the 20cm short primary cable helps to avoid cable clutter in typical applications, the included 30cm extension provides extra range for all cases. Both cables are fully sheathed.
SSO2 bearings
The NF-S12A is equipped with the further optimized second generation of Noctua's proven SSO storage system. At SSO2, the rear magnet sits closer to the fan axis, resulting in even better stabilization, resulting in further improved precision and durability.
Metal Bearing Shell
In order to guarantee the highest possible degree of manufacturing precision, minimum tolerances and excellent long-term stability, the NF-S12A uses a CNC machined bearing shell...
