> 3 daySupremely quiet in all orientations as all Noctuas are, but this is the only Noctua Ive found with adequate air flow on radiators. The only Noctua left on my radiators.

> 3 dayPut two of these in my airstream to quiet the noisy factory fan on the Refrigerator. They are super quiet and draw less current, less drain on the batteries

> 3 dayGreat overall, just -1 star for the choice of color. (but this would look great in a beige box from the mid 90s)

> 3 dayIve been having moments where the Cooler Master fans in my case were making some more noise than usual at times, and it concerned me that they needed replacement.Plus, those fans were a pain in the neck to have to install in the first place, having to carefully screw them in in steps to ensure the screws didnt strip while making a path for them to install into the fans plastic and into the case to hold them securely. The screw metals were cheap.

> 3 dayI love these fans. I replaced then because the original ones had gotten pretty dirty over the years. These are great. Very quiet and move a decent amount of air.

> 3 dayI love these fans - they move quite a bit of air, and I cant even tell that theyre running. I very highly recommend them!
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 FLX version provides 1200/900/700rpm speed settings via the supplied Low-Noise Adaptors in order to give you full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling
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.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe NF-S12A 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. |
Inner Surface MicrostructuresWith 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. |
Scope of delivery

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.
