> 24 hourReplacing all stock fans in a Corsair 240 with these. The Corsair fans make a slight tapping sound. The Noctua fans are very quiet.

> 24 hourI have bought many computer casings and computer casing cooler fans over the last 30 years. Noctua is the most quiet cooler fan I have ever purchased. I have install three 120mm fans in my little beast of a computer HAF-XB computer case and it is quiet. If you want quietness, try NOCTUA it the best. It probably cost twice the amount you pay for a standard fan cooler, it keeps the computer case cool and gets the job done.

> 24 hourMuy silencioso y de calidad como cabia esperar. No hago mediciones, pero si noto un buen flujo de aire y practicamente ni se oye

> 24 hourI had a CPU heatsink fan fail after many years of service. Replaced that fan with this one, because its in my HTPC and require as close to silent as possible, which this fan is. So far Im 18 months in of 24x7 with no issues. Its awfully dusty in its location too, so its been able to weather the dust

> 24 hourCe ventilateur a remplacé le ventilateur dorigine du NH-U12P SE2 qui ne fonctionne pas en PWM (détail qui mavait échappé à la commande). Il se fixe donc sans difficulté et le silence est au rendez-vous. Au fil du temps je me suis mis à apprécier ce look marron/beige très caractéristique de chez Noctua. Les coins en caoutchouc sont utiles mais senlèvent un peu trop facilement à mon goût ...

> 24 hourVentola di ottima qualità e silenziosa, cercherò di sostituire tutte quelle del pc con questa appena riesco. Bel packaging e molti accessori, sono davvero soddisfatto!
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.
