Noctua NF-S12A FLX ( 120x120x25mm ) [NF-S12A FLX]

Due to the optimized blade geometry with anti-stall knobs and the new AAO-frame (short for Advanced Acoustic Optimisation) of NF-S12A achieved compared to its renowned predecessors greater by up to 8% efficiency (output / noise). The FLX version allows using the supplied Low-Noise Adapters three speed settings (1200/900 / 700rpm) and offers full flexibility in fine-tuning between maximum performance and virtually silent operation. His outstanding quietness, the SSO2 reference-class stock and Noctua's proven premium quality make the NF-S12A to a fine choice for noise-optimized case cooling.

 Award winning S12 Design
The NF-S12A uses the third evolutionary stage of Noctua's classic straight blade design, the S12 series has countless recommendations from hardware enthusiasts and journalists registered around the globe. Next Optimised for an even better airflow / noise efficiency, it makes the NF-S12A ideal silent case fans.
Anti-stall Knobs
The anti-stall Knobs of NF-S12A reduce vortex shedding phenomena in situations with medium to high flow resistance and thus extend the so-called stable margin (stall margin). This makes the NF-S12A even more versatile than its predecessor and enables better results on heatsinks and radiators.
AAO frame system
Noctua's AAO (Advandced Acoustic Optimisation) frames have built-vibration buffer and a stepped inlet area (Stepped Inlet Design) and a microstructure inside (Inner Surface Microstructures), which enable even better performance / noise efficiency.
Stepped Inlet Design
Through the stepped inlet area of the Stepped Inlet designs created more turbulence in the feed. So the transition from laminar to turbulent flow is facilitated, better the frame adhering (Flow Attachment) and thus, in particular increasing the absorptive capacity of the fan with limited intake.
Inner Surface Microstructures
The microstructure inside the frame (Inner Surface Microstructures) creates a boundary layer, by moving the tips of the fan blades. This reduces the flow separation on the suction side of the blade tips, resulting in a considerable reduction in the Drehtons and an increase of the pressure and air flow efficiency.
Integrated anti-vibration pads
Made from extra soft silicone anti-vibration pads reduce the transfer minimal vibration and are also compatible with all standard screws and standard mounting systems or CPU coolers used fan clips.
3 speed settings for full flexibility
The NF-S12A FLX (Flexibility) via the supplied Low-Noise and Ultra-Low-Noise Adaptor 1200 900 and 700rpm settings and enables fine tuning for maximum flow rate or maximum quietness.
Smooth Commutation Drive 2
Latest enhanced version of Noctua's advanced SCD drive system ensures by eliminating torque variations and switching noises outstanding quietness. This makes the NF-S12A itself surprisingly quiet close.
Comprehensive connectivity options
During the short 20cm primary cable helps in typical applications, to avoid clutter, provides the supplied 30cm extension Extra coverage for all eventualities. Both cables are fully sleeved and a 3: 4-pin adapter enables direct connection to the power supply.
SSO2 stock
The NF-S12A is equipped with the further optimized second generation of Noctua grade SSO-bearing system. SSO2 at the back magnet is closer to the fan axis, thus causing an even better stabilization, resulting in a further improved precision and durability.
Metal bearing shell
To guarantee the highest level of manufacturing precision, tight tolerances and excellent long-term stability, the NF-S12A accesses a CNC milled back bearing shell made of brass.
6 years warranty
Noctua's fans are known for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-S12A an MTBF specification of more than 150,000 hours and is delivered with full 6 years manufacturer's warranty.
