> 3 dayIt is being used as a system fan one of two 120 mm fans mounted in the front part of my new NZXT S340 case and my AMD 8370 CPU temp stays well within comfortable ranges, even when under heavy usage. Note: I am not a gamer I only use my computer for video editing, graphics, cruising the internet.

> 3 dayInstallation is kind of a hassle but once you get it fixed in your case, youre looking at the most quiet and efficient 120mm fan you could ever buy. I have one for intake on the top of my case and it improved my CPU temps drastically.

> 3 dayI used it to cool a stereo cabinet in my RV. I used the low speed connector which is so quite you literally cant hear it.

> 3 dayProbably the best fans out there. They are super quiet, and come with many cabling accessories. They are brown and expensive, but they go inside the case so dont worry about the color, and the price is worth it.

> 3 dayThe only problem I had was trying to pull the rubber screws through the fan holes in a cramped space. I had better luck putting them in the fan first and then push the other side through the case. More color options would have been nice too, but I dont think they offer those in 3-pin models.
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 FLX version provides 1200/900/700rpm speed settings via the supplied Low-Noise Adaptors in order to give you full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. 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.
