> 24 hourI have used several types of Noctua fans in 3 different PCs that I have built. I have also used them as replacement fans when the original fans in several older PCs have needed to be replaced. The build quality of every Noctua fan that I have bought (approximately 12 in all) has been superb. Noctua has become my go to brand for PC fans. I have found none better!

> 24 hourI was worried about accidentally tearing off the rubber fasteners when pulling them through, but they all held up.

> 24 hourNot much to say -- theyre expensive but worth it. I have 5 in my case and never hear them, which is what I want in a fan.

> 24 hourNot much point in adding to what has already been said about these fans. Massive airflow and almost silent. Great buy if you looking for a fan that wont be pushing through a radiator.

> 24 hourDont plan on buying if your planning on doing any overclocking, otherwise, Noctua fans are about the best you can get for silence/airflow.

> 24 hourThis is an awesome quiet and high speed cooling fan. If yours is too loud, then try to reduce the fan speed manually to around 70% or so. If it runs on higher speed quietly then go with that too.

> 24 hourI 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.

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. |

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.
