> 3 dayOh, wow. For years I have been dealing with computer noise because I thought it was unavoidable, but this little fan proved me wrong. swapped out the radiator fan and another case fan with this and another Noctua product, and I cant hear either of them.

Greater than one weekNot quite what I was expecting. I hear a lot about Noctua, they are held in real high esteem among PC builders and enthusiasts alike. So it was a clear choice at the time of purchase. I bought it to replace the stock fan on my Cooler Master Hyper 212 EVO, but I was surprised to discover that this fan just isnt powerful enough to cool my i7-3770K at stock clock. I had to change the speed of this fan in the BIOS to 80% just to keep my CPU at an average of 28C to 30C. Decent fan, but not really meant for CPU cooling.

> 3 dayVentola super come silenziosità, molto bella anche esteticamente, oltre ad non sentire alcun rumore sono come base di appoggio e fissaggio ammortizzate negli angoli. Sono molto soddisfatto e contento del prodotto.Marca Noctua in assoluto per me la migliore!. Nulla lasciato al caso anche come confezione veramente molto bella.

> 3 dayQuesta ventola 120mm di Noctua è molto silenziosa ma senza trascurare l’efficienza; proprio quello che cercavo per sostituire la ventola anteriore del case. In molti dicono che il colore è brutto, ma devo dire che non mi da tanto fastidio, quello che ho notato subito è la cura di ogni dettaglio, un prodotto veramente di qualità.

> 3 dayThis is the king of quiet PC fans. I checked specs on a number of them, and none match this for both noise levels and airflow.
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 PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. 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.
