> 3 dayAnother great fan by Noctua. I have it mounted in the bottom of my Corsair 750D blowing up to my Graphics Card, and it is staying perfectly cool while making no audible noise.

> 3 dayUsed in a home theater PC. Didnt need the noise reducer. This thing is quiet.

> 3 daySiamo al top delle ventole: Noctua ormai non necessita di introduzione, e questa ventola ha confezione e dotazione degni di prodotti di ben altro costo. Rumore virtualmente zero., molteplici sistemi di fissaggio, prolunga PWN e riduttore di voltaggio corredano una ventola la cui qualità costruttiva appare evidente anche ad un occhio poco allenato.

> 3 dayIf youre seeking a silent pc, the newest sterrox A12x25 fans are not for you. Even with the ultra low noise adapter, the whooshing of the air is loud enough to be distracting. It is only quiet enough if you daisy chain the ULNA and LNA together, but at that point the voltage becomes too low and the fan starts to make a ticking sound (as it attempts to start and stop I presume). You may have better sound levels switching to the A12x25 ULN, but I personally switched to the NF-S12A instead for its superior airflow and lower noise levels (evident on the noctua site with around 10 decibels with LNA). I have the fans off at idle and have them ramp up under load. The NF-S12A does make sound as well, hence the 0 rpm mode set on my motherboard, but they do seem to be the quietest fans available that still provide decent airflow. The fans are impressive having the same noise level between 30% and 60% providing very high airflow with a quiet air being moved noise. Very happy with my NF-S12A purchase, got 3 of them in my Define C TG with a Noctua NH-D15 (set to minimum 20% rpm).

> 3 dayCome da titolo rispetto ad una Noctua P12 montata in estrazione in un case mini itx ho ottenuto temperature più alte di 2-3 gradi in stress test con Aida64. Il punto a favore di questa S12A risiede nella sua estrema silenziosità anche al 100%, suppongo che la discrepanza nei risultati risieda nella particolarità della mia situazione. Comunque è la migliore ventola che ho mai provato quanto a silenziosità in rapporto alle temperature, tantè che comunque ho lasciato questa installata nel pc

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.
