Noctua NF-A20 FLX

Quiet box fan 200mm

Last price 44€95
Holy Moly!
Overview
Exceptionally quiet!
The NF-A20 is a high quality, quiet Noctua fan in 200mm format that meets Noctua's AAO (Advanced Acoustic Optimisation) standard. Featuring the latest advances in aerodynamic technology, including Flow Acceleration Channels
, the NF-A20 takes the cooling performance for which they are renowned even further.
The FLX version allows for speed adjustment to 800/500 rpm with the included low noise adapter (LNA). The NF-A20's amazing discretion, the presence of SSO2 reference bearings and Noctua's guaranteed quality level make it the ideal fan for the most demanding users.

Smooth Commutation Drive 2
Noctua's latest SCD system ensures smooth operation by eliminating torque variations and switching noise. As a result, the NF-A20 remains very quiet even at close range.
Extensive wiring options
The first fan cable is a short 20cm, which minimises the space required for routine use. 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.

    Ouch, what a pain in the ass

    Hello, the assembly should be easy if you have what to do. I explain: my antec nine hundred case is designed for a 20cm fan from antec, this noctua model had to undergo some small modifications to fit. I thought it would fit like a glove, but it didn't. But everything is installed, it blows the air well as expected.
