> 3 dayI buy 2 of these to change the stock fans of my CISCO SG-500 because of sound they produce. It annoying because its near in my bedroom. Installation is a bit tricky because i need to change the pinning assignment of nuctua. Installation is easy to mount with lots of adapters included in the nuctua fan which is mosltly i dont use. One thing i dont like is after i power up the switch, the cisco have a warning, sad to say the switch cannot recognize both fans which i see in webserver of the switch.

Greater than one weekI bought it to change a noisy fan in a rackmounted switch.

> 3 dayJavais fais confiance a Noctua sur ce coup, mais très décu, il a grillé quelques mois après son utilisation. Dégouté !

> 3 dayIts quite and does its job. I replaced a Security camera fan and it is night and day. Build quality very good. If you want to be picky, the color. I didnt care about stuff like that and I am not trying to impress anyone. It has a job and it does it without breaking.

> 3 dayHabe diese Lüfter zum Umbau meines Kingroon 3D Druckers verwendet, dessen Lüfter ab Werk eher einem Düsentriebwerk ähneln. Seitdem hört man nur noch ein leichtes Surren und selbst das Netzteil ist lauter als der Drucker selbst. Als nächstes wird dann wohl der Lüfter dort mit einem Noctua ausgetauscht :)

Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 FLX is a highly optimised, premium quality quiet fan in 40x10mm size. Smooth Commutation Drivetechnology and Noctua’s reference class SSO2 bearings ensure superb running smoothness and excellent long-term stability. Topped off with modular cabling and a Low-Noise Adaptor and OmniJoin Adaptor Set, the NF-A4x10 is a premium 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-A4x10 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-A4x10 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 mounting systems and fan clips used on heatsinks. |
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. |
Reduced motor hub size
Thanks to its streamlined, compact motor design, the NF-A4x10"s motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10"s superior airflow and pressure performance.
