> 3 dayNeeded to replace a noisy stock rear Case Fan. This was our, Go To brand of choice. Connected directly to Gigabyte GA-990FXA-UD5 Motherboard. Satisfied with Air Volume vs Noise. This Fan should outlast this PC System Build!

> 3 dayHo corredato il mio computer di 4 di queste ventole, più una NF-P12 PWM sugli hard disk , dopo aver provato la qualità Noctua con il dissipatore NH-L12.

> 3 dayBought to replace a similarly priced fan from another well known company that was already failing. Easy to replace the faulty item, even for me, and PC is now completely inaudible when running.

> 3 dayOttime ventole e specialmente silenziose, muovono parecchia aria allinterno. Sono eleganti e sobrie con il loro classico colore, non sono RGB ma fanno il loro lavoro aldilà delle tamarrate presenti in circolazione con luci e lucine e un rumore assordante.

> 3 dayThis 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 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

> 3 dayArrived quickly, adequately packed. Have used Noctua fans for years, no failures to date. Have at least dozen in service of different sizes. They are very quiet, provide good flow and pressure. I always replace standard products with these in any new build.

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.
