Greater than one weekI used this as a low noise swap for my ender 3 hotend and it brought the idle noise down a lot. Not sure about the other fans when replaced though. Keep in mind this does need a step down converter for use with the ender 3.

> 3 dayIve used this fan as an upgrade from a generic 40mm fan I was using on a printed hot end fan / shroud on my Monoprice Select Mini 3D. This fan is night and day better than the fan it replaced. It moves plenty of air, but the HUGE win with this fan is that it is dead silent. It is so quiet that you almost dont believe your eyes that the fan is actually running. It is no wonder the new Prusa Mk3 uses these fans. They are amazing!

> 3 day...leider zuwenig Luftdurchsatz am Original Hotend vom Anycubic. Habe die Lüfteröffnung am Gehäuse des Hotends ausgefräst.

> 3 dayExcellent. The wire joining terminals (scotchlok) made by 3m is super easy to use and prevents the use of unreliable solder or lug joints.

> 3 dayWer Noctau kennt weiß, dass es sich in aller Regel um sehr gut verarbeitet und langlebige Lüfter handelt. Zumindest in dem ersten Punkt ist der NF-A4x10 FLX keine Ausnahme, die Langlebigkeit kann ich schlicht noch nicht bewerten, aber auch da wird meine Erwartungshaltung gewiss nicht enttäuscht.

> 3 dayBin sehr zufrieden, mein Ender 3v2 hört sich spürbar leiser an. Würde ich wieder kaufen. Und ist zu empfehlen.
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.
