> 24 hourWith the ULNA (ultra low noice adapter) the fan is absolutely silent. No high pitch noice and is much much better than my old fan.

> 24 hourI 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.

> 24 hourBeen buying Noctua fans for years. As always, they are well made and quiet. A bit pricey, but worth it in my opinion.

> 24 hourAt first i was skeptical at first as i never tried Noctua product but well all i can say is it impress me.. Noctua Fans are really well made and at full speed of about 1450 they are barely audible

> 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 hourMy case was generating more heat than my CPU heatsink was able to deal with, so I installed this as a secondary fan. Quiet, easy to install, and has kept my temps nice and low

> 24 hourThis fan is much louder than I expected given its raving reviews and premium price. This 120mm fan is very audible even from 5 feet away and inside a sound dampening case. The 140mm fan on the other hand is totally silent.

> 24 hourYes, theyre great and super quiet. I put 2 of them in the top of my new Corsair 650D case. fit perfect and was easy to plug right into the motherboard, came with multiple extensions and connector cables to try. Simple, QUIET and efficient. I replaced the stock case fans that werent bad, but just had a noticeable amount of noisy that got to be distracting.
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.
