    Greater than one week

    Quiet operation with lots of air flow. Some people gripe about the color but theres no denying the performance of Noctuas fans. I dont concern myself with the color of it considering its behind a grill.

    Ok

    FYI - The one and only reason I am not considering this fan is because there is no CFM listed. However relevant the measurement may or may not be to enthusiasts, I need to compare a general measurement of airflow for a fan. This could be the weakest fan ever manufactured for all I know, which is great for silence and terrible for my use case.

    Brought my motherboard temps down to 30 C. My processor temp now runs at 56 c when doing a security scan on my 500gb ssd, temp drop when scanning a conventional hard drivr is now 45 - 46 c

    absolute best fans that I have ever used. Good air flow and still extremely quiet for the air flow that they provide.

    My stock case fans leave a bit to be desired when it comes to be quiet. I replaced them with a pair of these. Running them at 450 RPM, they are inaudible. It isnt until about 750-800 RPM until they get audible (barely), and it is the movement of the air, not the fans itself.

    ottima ventola, rumore bassissimo e portata daria notevole. Si installa facilmente ed ha diversi accessori e prolunghe. Vedremo se la rumorosità rimane bassa anche con il passare del tempo

NF-S12A PWM HeaderNF-S12A PWM Header

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 pads

Integrated 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 bearing

The 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 Microstructures

With 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

  • NA-RC7 Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws

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.
