> 24 hourI wish Noctua would come up with a different color option, but Im will to deal with that for the quality of this fan. Extremely quiet and moves lots of air. I replaced all of my case fans, and its now very easy to forget my computer is even on.

> 24 hourSupremely 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.

> 24 hourDespite the stellar reviews, I didnt expect much out of these little fans. I mean, at the the end of the day, its still just a fan.

> 24 hourI recently built a new high performance PC with (2) M.2 drives that kept getting a bit warmer than I would like. They were running just over 50°C. I bought 2 of these fans to help move more air across the M.2 drives. They provide all the hardware to install the fan either with the rubber prongs or screws. Several power adapter cables are also supplied. The fan feels sturdy and was pretty quiet. My M.2 drives are now in the lower 40°C range. The frame has rubber that appears to keep any vibration or rattling down.

> 24 hourTheyre not as quiet as I was led to believe from other online review sites, I can still hear the air wooshing when the fans are at 900rpm (using the L.N.A), but at the same time they make an agreeable sound that doesnt annoy me as my previous Cougar Vortex fans did with their higher pitched wooshing.

> 24 hourI replaced the fan on my Cooler Master Hyper 212 EVO CPU Cooler with this fan; slightly better temperatures, much quieter performance!
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.
