30-10-2024Its 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 dayBeh...che dire....qualità noctua. impressionante come una ventola così piccola sia così bella. unica nota negativa è il flusso daria, molto silenziona ma pensavo un flusso maggiore

> 3 dayVery good quality and so quiet. About 2/3 the price went into packaging and wire adapters.

> 3 dayI use this on my 3d printer (AM8 with SKR v1. 3) in place of the standard hotend fan, set to 60% by default. At this speed, its hardly noticeable when its the only thing running. Even at 100% its still quieter than the motors and steppers.

Greater than one weekJai posé 2 de ces petites chose sur une alfawise u20, reduit considérablement le bruit surtout si couplé à des damper pour moteur pas a pas.

Greater than one weekOttima ventola silenziosa in assoluto la migliore con tanti accessori per isolare il rumore con appositi chiodi in silicone e cavi tra cui uno per ridurre il rumore ulteriormente abbassando il numero di giri da 4500 a 3700..cosa altro dire?
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.
