> 3 dayI bought this fan to replace my CPU fan. Its excellent. Very quiet and includes 2 cables: power extension and PWM Y-Splitter. I ended using the Y-splitter elsewhere in my system. I appreciate the short power cable, perfect length for using it as a CPU fan. The power extension is usable if you want to use it as a case fan.

Greater than one weekIt is quiet and effective. I love Noctua, high quality and I even got used to the weird colors. Lots of airflow from a small fan.

> 3 dayReplaced the stock case fans in my NZXT H510. The fans it comes with arent bad per se, but Im easily annoyed by noise. These fans give me exactly what I want, which is absolutely no noise other than the sound of air moving. The rubber anti-vibration mounts are a must for these, metal screws vibrating can cause noise. The color scheme of these fans seems to be controversial among pc builders, but beige is my favorite color, lol. By the way, when I bought this on Amazon, I was shipped the ones made in China, not the ones from Taiwan (not actually sure if they are still manufactured there). If youre out of the loop, a fan manufactured in Noctuas China factory had color differences from a fan from the Taiwan factory (there was some reddit drama over this at some point). As far as Im concerned, as long as the two I have are from the same factory (which they are) then Im fine with 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. |

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.
