> 3 dayNoctua is SO GOOD!!! I was so excited when I found this 40mm for my 3D printer!! Talk about reducing the noise of a printer, the fans are the best place to start! Love it!

Greater than one weekTrès bien, silencieux, en revanche, le prix est un peu élevé et la couleur laisse à désirer (marron - beige)

> 3 dayNot sure why these have such good reviews, supposed to be near silent yet it was much louder than the one I was replacing which was supposedly a cheap manufacturer supplied one.

> 3 dayCon questa ventola, montata per raffreddare lestrusore di una stampante 3D, questultimo non riusciva a raggiungere le temperature sopra i 190 gradi poiché la ventola dissipava il calore in eccesso, ho dovuto modificare il condotto di raffreddamento per permettere lestrusore di prendere la temperatura corretta

> 3 dayle ventilateur est trés silencieux mais bien trop cher pour un si petit, il y a un gros packaging pour lemballage du ventilateur et je me demande si cest pas ça qui coûte le plus chère. finalement je lai retourné et jai trouvé mon bonheur dans une autre marque bien moins chère et tout aussi performant.

> 3 dayMuchless harmonics in the frame and audible noise than others I have used. Highly recommend if you dont need the higher RPM. I used this on an Anet A8 Extruder.

Greater than one weekWhat can I say... Noctua is easily one of the best fan manufacturers around. Period. Ive been using their fans for years without a single issue. For a few extra dollars compared to the other choices, they cannot be beat in my opinion! This was used as a direct replacement for the failing CPU fan on a generic PC at work. I dont know the specs of the 40x10mm that it replaced, but the PC now seems to be running smoother. I suspect that the stock fan was not moving enough air, even before beginning to fail.
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.
