Set Alert for Product: NF-A20 PWM Boitier PC Ventilateur 20 cm Beige, Marron, Ventilateur de boîtier - 36,29€
The NF-A20 is a high quality, quiet Noctua fan in 200mm format that meets Noctua’s AAO (Advanced Acoustic Optimisation) standard. It benefits from the latest technological advances in aerodynamics, including Flow Acceleration Channels.
Description
Exceptionally quiet!
The PWM versionfeatures the proprietary NE-FD1 IC that allows fully automatic speed adjustment via the 4-pin fan connectors. It includes a Low Noise Adaptor (LNA) that caps the maximum speed during PWM drive. Its amazing discretion, the presence of SSO2 reference bearings and the quality level guaranteed by Noctua make the NF-A20 the ideal fan for the most demanding users.

 | Exclusive PWM IC with SCD The NF-A20 features the latest NE-FD1 PWM IC with Smooth Commutation Drive (SCD) technology. By generating less abrupt torque pulses, SCD eliminates the noise associated with PWM switching for quieter fan speeds. |  | Extensive wiring options The first fan cable is a short 20cm (8″) cable to minimise space requirements for common applications. The supplied 30cm extension cable will solve any distance problems. |
 | Flow Acceleration Channels The NF-A20 is equipped with flow channels on the suction side of the fan. The flow acceleration generated at the tips of the blades creates a more massive, less dispersed suction, thus increasing efficiency. |  | AAO frame Noctua’s AAO(Advanced Acoustic Optimisation) frames are equipped with anti-vibration mounts and benefit from exclusive optimisations to push the limits of performance and silence. |
 | Stepped Inlet Design Noctua’s Stepped Inlet design adds turbulence to the inlet flow, allowing a gradual transition from laminar to turbulent flow. This reduces noise emissions, generates a more massive flow and increases suction power. |  | Inner Surface Microstructures As the blade tips move in a boundary layer influenced by the presence of an Inner Surface Microstructure, the flow separation that takes place at the suction level becomes almost non-existent. |
 | Integrated anti-vibration dampers The integrated anti-vibration mounts, made of extra soft silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard fastening systems. |  | SSO2 Bearing This is the latest generation of the SSO2 bearing, which is even more optimised. The SSO2 is equipped with a rear magnet closer to the axle for greater precision, durability and stability. |
 | 6-year manufacturer’s warranty Noctua fans are renowned for their quality and durability. As with all Noctua models, the NF-A20 has an MTBF of over 150,000 hours of testing and is backed by a full 6 year manufacturer’s warranty. |  | Low Noise Adapter The NF-A20 comes with a Low Noise Adaptator (L.N.A.) that drops the maximum speed from 800 to 550rpm. The L.N.A. is suitable for both fixed speed operation and PWM clamped operation. |
