> 3 dayQuiet, works great, easy to install with a variety of power connection options - highly recommend! People have pointed out that it has an ugly color scheme, so what? Its inside the case.

11-06-2025With the ULNA (ultra low noice adapter) the fan is absolutely silent. No high pitch noice and is much much better than my old fan.

Greater than one weekI replaced the fan on my Cooler Master Hyper 212 EVO CPU Cooler with this fan; slightly better temperatures, much quieter performance!

> 3 dayI had purchased an NZXT Manta and a NZXT Phantom 410. Both with stock NZXT fans. All the fans on both PCs slowly went out over the course of 2 years. They would start ticking. I eventually replaced them all with Noctua fans. I had initially put an Noctua cooler on my CPU and loved it. So, now both PCs have all Noctua fans and theyre very quiet. Ive had my cooler fan for 5 years and the rest for at least 3, none of them make any noise what-so-ever. The installation is quite easy as they have screw-less rubber fasteners, I have used them on 2 of the fans in my PC, they work great. They come with all the cables you would need, all wrapped and very clearly labeled. I highly recommend anything from Noctua.

> 3 dayI hesitated a little when I purchased this, because of the price and its color. However, as soon as I plug it in, I was very very happy with the performance. Probably the quietest fan Ive ever used and yet still has great airflow. Everything about the fan is great(from the product itself, the accessories that came with it, to the design of the box), I felt very satisfied. Would totally recommended to anyone that dont care a lot about it color scheme, the fan is suppose to be inside the case anyway.

> 3 dayGot a 4000D Case for airflow and already had 2 of these fans when I upgraded and they are less than half as noisy as the ones from Corsair

> 3 dayI have 3 of these fans in a Lian-Li PC-04B on low and they get the job done fantastically! (No Pun Intended). They are quiet and move quite a bit of air even with my fan controller on low.
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.
