> 3 dayThis Noctua NF-S12A case fan is as good as Ive seen in terms of build quality. Even box the fan is supplied in immediately sings quality.

> 3 dayThere are extremely quiet Case Fans especially with the included low noise adapter, must admit little bit on the expensive side but if your looking for quality its right here

Greater than one weekQuiet, moves a lot of air and excellent replacement for my case fans.

> 3 dayNoctua sempre al Top. Acquistata per muovere piú aria nel mio case NZXT H440 visto che ho inserito un ulteriore harddisk che, a causa della sua posizione, tende a tappare le 3 ventole frontali montate nel case

> 3 dayThis fan can stop completely at 9% PWM. This is useful because not all system boards can send a real 0% signal if needed to really have fanless mode sometimes.

> 3 dayReçu récemment pour remplacer le ventilateur de mon ventirad watercoolé Corsair. La différence est flagrante! Très silencieux, refroidit très bien mon Core i5 8400 (moins de 30° en idle). Noctua fait des merveilles avec ses ventilos.

> 3 dayOttima ventola da 12cm utilizzata per limmissione di aria allinterno del cabinet. Utilizzata in PWM con il controllo della velocità in base alla temperatura interna risulta essere sempre silenziosa nel suo funzionamento anche al salire dei giri. Inoltre scatola completa di numerosi accessori cavi e adattatori.

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.
