> 3 dayGreat quality. The packaging was very high quality. I am not sure they are as silent as people make them out to be. I think most fans at 700rpm will be pretty quiet. Above 1000 rpm they are audible.

Greater than one weekWhen I originally built my computer I cheaped out and bought $5 fans and regretted that choice for about a year until I bit the bullet and bought two Noctua fans as case fans. They are worth every penny! Super quiet with very premium build quality. Ive had them for over three years now with no issue and theyre just as quiet as the day I got them. Dont make my mistake and invest your money in premium fans, your sanity will thank you.

> 3 dayThe hype on these fans are well deserved. They push a good amount of air and are extremely quiet even going at full speed. As for the color, its a fan so I could care less. You cant beat the warranty which dwarfs other companies. I highly recommend. These will be running 24x7 so I needed something reliable and quiet.

> 3 dayThis a great cooling fan, because it is extremely quiet. I have one of these in my bedroom cooling a DVR, and you can not hear it running at night when it is very quiet in the room. Note that I am using the fan with a 9 volt calculator type power pack, so the reduced voltage makes it quieter then the normal 12 volt.

> 3 dayI love these fans. I replaced then because the original ones had gotten pretty dirty over the years. These are great. Very quiet and move a decent amount of air.

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.
