> 3 dayThe Noctua NF-S12A is a high-quality 4-pin PWM fan. I am using one as an intake fan in the front of my computer case. I like the fact that the fan comes with so many accessories. The fan comes with an extension cable, a cable splitter if you want to run two fans (at the same speed), and a low noise adapter to reduce the maximum speed from 1200 to 900 rpm. Not that I want to reduce the speed of this beauty.

> 3 dayMy case is a Cooler Master HAF XB EVO. It comes with 2 stock 120mm fans in front and space for a 120mm fan in the rear. I ordered a fan for the rear and it is good. I just ordered two more Noctua fans and will replace the stock fans in the front of the case.

Empirical experience
> 3 dayWhisper quiet. Cant tell if PC is on sometimes. Did not use low rpm adapter.Replaced 3 Antec 1600 RPM 56 CFM basic fans.

04-04-2025No complaints. Install was easy. The fan is very quite. I have it set up to pull air through my Rad. It would probably work better pushing air, but its not given me any issues. Its quite and my CPU temps are consistently below 45 deg C. (I5 2500K processor not overclocked in a P280 case with all 7 fans installed)

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.
