> 3 dayI installed two of these on my Wanhao i3 3D printer. I was hoping to see some noise reduction but what I didnt expect was -- silence. These two babies, plus a large fan to replace the fan in the power supply and control unit, and the i3 has turned from the noisiest printer to the most quiet in my small print shop. Should have done this a long time ago.

> 3 dayWhisper quiet! SO MUCH BETTER than the stock CR-10/CR-10s/Ender 3 Fan.

> 3 dayNice addition to my Ender 3 Max...much quieter. Excellent selection of connection wiring and mounting options with it too.

> 3 dayBought these to use on a 3D Printer in place of the originals that permanently screamed at full speed. I really find it hard to tell if they are on or not without looking or putting my hand in the airflow,

29-09-2024I was looing for a quiet fan for a NAS that I was building. My goal was to make the NAS as silent as possible. This fan is barely audible and moves a sufficient amount of air to keep the NAS cool. A great buy.

Greater than one weekThe Addition of this Fan has Reduced the Noise a great deal compared to the Stock Fan.

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.
