Product Description


The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. 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 2200 to 1750rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

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.

Flow Acceleration ChannelsThe NF-A8 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 bearingThe NF-A8 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. |
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. |
Scope of delivery
|

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.

Noctua is very deserving of their good reputation.
The sound dampening screw alternatives aren't necessary in this case, as I installed one fan with the basic screws that came with it and haven't heard a thing. So don't worry about getting the little stretchy suckers on in the hard to reach corner position.
Noctua delivers, as always, a primo product.

*VENTAJAS:
- Calidad demostrada por una marca que jamas me ha fallado
- Sonoridad respecto a la competencia muy inferior
- Calidad de construccion
- Viene con reductor de RPM y anclajes especificos para su sujeccion
*DESVENTAJAS:
- Precio elevado en todos los productos de esta marca
- Colores algo feos



Io le uso per scopi audio per raffreddare elettroniche ad alta potenza e ovviamente oltre all'efficienza dinamica è molto importante l'inquinamento acustico.
Usate anche a basso voltaggio è praticamente impossibile sentirne il rumore anche nei silenzi musicali ,ovviamente almeno a 50/60 cm!!! Non chiedete l'impossibile!
Amazon? Motori pari avanti tutta!!
