> 3 dayI bought my first Noctua fan (NF-P12) to replace the one that came with my aging CPU cooler, and was satisfied enough with it that I bought a pair of these NF-S12As to replace my intake & exhaust fans. I had read ecstatic reviews about these dropping case temps by like 10 degrees, but I didnt count on it (or frankly believe it). So long as they kept my case as cool as its stock fans but QUIETLY Id be happy.

> 3 dayAdding just one of these to my NZXT H230 dropped my Sapphire Radeon VAPOR-X R9 280X Temp by 5C while playing Sniper Elite 3. I got one empty spot and 2 stock fans I want to replace. Ill be getting 3 more of these.

> 3 dayPerfect inside my Node 804 case. I have 6 of these puppies running to keep my FreeNas system cool and quiet. This are inaudible when running at 600rpm. These are the PWM fans, so voltage and fan speed are controlled via your motherboard. I just wish these came in black.

> 3 dayLove these fans. Noctura is my favorite fan company now and I will always buy these they with great and helped lower the temp in my pc by a large amount.

> 3 dayAside from the look, this is an awesome PWM fan. Very silent, and well designed. I switched all the fans of my case to this model and end up having a powerful gaming computer that is silent quiet when used for web, browsing and (very important) video watching.

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.
