> 3 dayI bought this for my ender 3 3D printer hot end cooling fan. It’s very quiet and comes with all kinds of adapters and mounts. The rubber corners and quality motor mean this fan is incredibly quiet.

> 3 dayThe USG-PRO-4 comes with fans that are louder than these, but that isnt a dealbreaker. The dealbreaker is the high-pitched whine. Like a banshee is trapped in the router and is emitting a frequency that I can hear from four miles down the road while wearing earmuffs and watching fireworks. Its hellish.

> 3 dayUtilisé pour remplacer le ventilateur de mon imprimante 3D. Elle est devenue (presque silencieuse).

> 3 dayHigh quality product. It comes with practically every cord, connector, and mounting pin you would need for any situation with this fan. I have to put my ear right up to it to hear anything while running.

> 3 dayI had to check that these things were actually spinning a few times because I just couldnt hear them. Great quality as always.

Greater than one weekUtilisation pour apporter un flux d’air dans mon très petit boîtier (type Pc ) il tourne à 4500 tours minutes et reste peu audible à plein régime.

> 3 dayI use this for my 3d printer and cam only tell its on by looking at it. Which sometimes isnt good but I am in no way complaining. Recommend this fan if you have a printer to cool your hotend. Comes with a bunch of extras.

> 3 dayNulla da dire funziona bene, non da noie ed è silenziosa, ma non fa nulla in più di quello che fanno altre ventole che possseggo e che costano un terzo.
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.
