> 3 daySenza dubbio le migliori ventole presenti sulla piazza, che senza dubbio si fanno sentire in termini di spesa. Muovono un sacco di aria, a distanza di anni sono ancora silenziosissime e se proprio non vi piace il marroncino tipico di Noctua potete sempre prendere le colorazioni differenti a un leggero sovrapprezzo. La qualità si paga, ma in compenso non esistono alternative più prestanti per il mercato consumer.

Greater than one weekThese fans are the real life equivalent of hooking up with a retired mute prostitute. Theyre quite expensive, ugly as sin, but they really get the job done, and super quiet!

> 3 dayAs described, it is VERY quiet (especially when compared to the expired chassis fan that I replaced with it), and it moves a lot of air---no way to measure it scientifically, but the deflecting paper test suggests that the claimed CFM rating is probably close (obviously it will differ depending on the differential in static pressures on either side of the fan). Anyhow, it works for me.

> 3 dayA truly excellent fan - I was looking for something with strong performance and quietness. This fan delivers in every sense of the word. Using this as an exhaust behind my CPU, I saw not only a decrease in idle & load temperatures but a noticeable improvement in the noise department; this was a welcome change from the noise pollution brought on by my previous exhaust fan, a CM Jetflo.

> 3 daynoctua nf-s12a pwm fan is quiet i really like it you can set the rpm to what ever you like dont case about the colour not in to all this gotta look good i just want my pc to run so i orderd 2 more now am broke for 2 weeks lol when i have the money i will get a noctua nh-d15 cpu cooler

> 3 dayThis fan is not that quiet. I got this fan because of the lower max rpms and supposed lower dbA since I have a 3 pin header, I figured a l.n.a. would be enough. Lo and behold it isnt, I even hooked up 2 l.n.as to slow the rpm even more but I can still hear it. According to speedfan 1 l.n.a dropped the rpm from 1200 to 1050 instead of reported 900, and 2 l.n.as dropped it to 950. Either the software is inaccurate or the resistors were off.

> 3 dayI would never think a fan is worth this price but I took a chance to replace a noisy fan on a liquid CPU cooler. This thing is super quiet and keeps my CPU cool.

10-06-2025Replaced the factory intake fan and exhaust fan with an F12 and S12 and noticed a 18dBA difference about 3 feet from my case, which is insane (about 1/4 the perceived volume). Quiet as a whisper and really easy to install.
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.
