> 3 dayso quiet that i had to look see if it was working -- only problem is that i was a but clumsy installing one and pressed on one of the fan blades and broke it - spins but as off centre now need to order another to replace the one that I damaged

Greater than one weekI have replaced all of the case fans for my wifes and my desk tops. I have used Noctua for years and have never had an issue, I just wish my power supply fans on my computers were as quiet!! Great fan, well worth the price, you will be amazed at how loud your old fans are when you switch over to this fan. I have used these on very high end gaming computers as well as mid priced work computers and am very happy with the performance.

Greater than one weekOutstandingly quiet at any speed while delivering high airflow. For the price, Noctua had produced a fantastic product.

> 3 dayPicked up another one of these fans to add to the other one that I had from a previous build. These fans (Noctua) meet all rave reviews about them. They are completely silent in setup.

> 3 dayVery solid construction. I love that it comes with extension cable, rubber mounts and screws. I intend to replace the rest of my fans with these or similar.
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.
