> 3 dayI am using the Noctua NF-S12A (4-pin) fan as a single exhaust fan with no additional case fans. I replaced an Antec Silent variable speed fan that came with my case when the bearings started to go. I thought Antec fan was quiet but the Noctua NF-S12A is essentially silent when running idle add pushes a lot of air. The Noctua NF-S12A fan is a little pricey but this fan is exceptional. The fan comes with rubber anti-vibration connectors, an extension cable, a y-extension cable and a low noise adapter cable (has a resistor to slow fan speed down. I have the case mounted under the desk and even without using the low noise adapter or the anti-vibrations connectors, the fan is silent. I would highly recommend this fan for anyone concerned about noise in small shared spaces.

> 3 dayUn poco caro, pero vale lo que cuesta. Aspecto robusto (no es de plástico barato como muchos otros), tiene pinta de estar hecho para durar. Muy, muy silencioso; casi imperceptible por la noche (cuando casi no hay ruidos). El caudal de aire es perfecto, esta muy bien diseñado. Viene con todas las conexiones posibles y tornillos. Volveria a comprarlo.

> 3 dayIl top tra le ventole, vale veramente la pena spendere qualche soldino in più per questa ventola silenziosa e potente allo stesso tempo!

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.
