> 3 dayThese fans are made by an Austrian company dedicated to air cooling, and the quality of the engineering is unsurpassed. Each pack includes all adapters and mounting accessories necessary. The fans push a lot of air, are very quiet, and, in my experience, outlast all cheaper fans (the latter start to rattle after a few months of use).

Greater than one weekUsing it in an entertainment center in the living room to exhaust the hot air from the cabinet storing my cable modem, Router, and switches.

> 3 dayCase exhaust/intake fan. As quiet as they come and hooked up to a fan header. Im very happy with all my noctua gear, and from reviews, wouldnt buy anything else. Quiet results are worth the money.

> 3 dayI replaced the default fan that came with the Corsair Hydro CPU cooling system with this fan, and it cut the system noise in half on max power. Hooked it up to a fan controller and its whisper-quiet at minimum. The moment I picked up the fan I could tell it was of far superior build quality than the other 120mm fans I have used in the past. The packaging also deserves praise: everything is clearly labeled and easy to access.

Greater than one weekIve been reading and hearing good things about the Noctua products and fans and decided to give them a try in my new build. I purchased two of these fans for exhaust and they work great, variable speeds which I can adjust via my motherboard, and the quality of these fans surpass any other fans I have purchased in the pass, they provide good air flow and are extremely quite. Nice product, I would purchase again and highly recommend.

> 3 dayI am using four of these fans in a Corsair 540 case, and the fans run completely silent! The mounting can be a little bit difficult at times, but the overall a great fan design. Airflow is excellent, oh and I didnt notice any issues with the high pitched noise other reviews mention.

> 3 dayIm sure this is a perfectly decent fan. But it will not work for my specific circumstances. This fan will not fit in a Corsair Obsidian 800 D case with an H100 cooling system in it.

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.
