> 3 dayThis fan can stop completely at 9% PWM. This is useful because not all system boards can send a real 0% signal if needed to really have fanless mode sometimes.

Greater than one weekAfter receiving this on Monday I must say Im extremely impressed about how quite the fan is and it keeps my pc cool about the same as my old fan except its more quite... The only issue I have with is the y splitter cable... One of the 4 pin connector in the y splitter cable is missing a pin right in the middle essentially making it a 3 pin... so its like 2 pins, blank and pin.... I will atach a picture to show below

> 3 dayThis fan is great! It runs silent, moves a good amount of air, and has good static pressure (which is great as I have this in front of my radiator). Ive seen people complain about the color scheme, white and maroon will not match with any other components Ive seen. But I really dont care about the look (windowless case) as long as it runs well. And boy does this baby run smooth.

> 3 dayVery quiet fans. I have a total of 8 noctua fans in my system. 4 are set to max rpm and the loudest fan in my system is the psu fan. My system stays cool as well.

Greater than one weekOne of the fans in my System76 Leopard Extreme started making noise...which is a big no-no for a system being used in a recording studio. I had to replace it with a fan that would add nothing to the noise floor. This baby is IT! The second I plugged it in, I had to put my ear up to the open case in order to hear it.
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.
