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 Optimisation) frame,
the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The ULN version provides super-slow 800/600rpm speed settings for ultra-
low-noise applications and highly noise sensitive users who demand near-silent operation. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium
quality make it an elite choice for quiet case cooling.

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 ULN is even
more versatile than its renowned predecessor and can achieve better performance on heatsinks
and radiators.

and radiators.
Flow Acceleration Channels
The NF-S12A ULN impeller features suction side Flow Acceleration Channels. By speeding up the
airflow at the crucial outer blade regions, this measure reduces suction side flow separation and
thus leads to better efficiency and lower vortex noise.

AAO Frame
Noctua’s AAO (Advanced Acoustic Optimisation) 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 ploughing 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.

SSO2 Bearing
The NF-S12A ULN features the further optimised 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
stabilisation, precision and durability.

Smooth Commutation Drive 2
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-A14 remarkably quiet even at very close distance.

Extensive cabling options
The fan’s short 20cm primary cable minimises cable clutter in typical applications while the
supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved
and the supplied 3:4 pin adaptor allows to connect the fan directly to the power supply.
