15-06-2025This fan is amazing, I cant hear it over my other case fans. I use it to pull air through a liquid CPU cooler and it keeps temperatures in the 36 to 56 C range, idle to full load respectively). You really cant beat this.

> 3 dayNoctua e basta, si riesce solo a sentire laria sulle mani, il rumore è talmente fastidioso (scherzo!) che non so se è in funzione oppure no.

> 3 dayOnly had the fans a short while [1 week] but they have sunk my temperatures by 10-20degrees on idle whilst remaining at low noise. The only reason this is given 4 stars is because despite all the extras included in the box, the mounting option is soft plastic that bends so much, I cant fit it easily through the hole on all 4 sides due to case access restrictions for the top most case fan. So I gave up and used a screw...or at least tried to, but then realised these werent able to fit the case I have [a now dated Antec P180]. A great case however - after 12 years. The good news is, 4 stars only for my experience. You might have a 5* experience. Advice to anyone buying these, expect to use screws if fitting this somewhere fiddly, unless you have ninja-like finger abilities :D

> 3 dayWhen it comes to fans you cant get better than Noctua. I replaced 3 of my Noctua NF-F12 PWN case fans with these. They flow better and they are quieter. I cant hear them when they run.

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.
