> 24 hourThis fan is awful.. I feel like Ive been taken for a ride. For years I hace watched YouTube videos like Linus tech tips who praise these fans like crazy. This is the first time I finally buy one and it BARELY pushes any air... I thought something may be wrong so i hooked it up to my home made bench power supply. I pushed it to 15 volts and sure, it pushed more air and was still quiet....but not NEAR what i was expecting for the price. Very disappointed. ( I am using this to cool my 3D prints. I went from using a loud blower fan to this....just because this didnt do anything, I learned fusion 360 and built an adapter for the blower fan to mount up to where I needed this 40mm fan. Again, if u want any air to flow over your parts, dont buy this.

> 24 hourqueste ventole sono di altissima qualità.sostituita a una stampante 3d in quanto la sua originale era molto rumorosa.

> 24 hourMir gefällt der Lüfter wirklich gut, habe den in meinen 3D Drucker eingebaut, ist echt um einiges leiser geworden. Die Kühlleistung ist auch mehr als ausreichend.

> 24 hourNo fan is silent, but these come pretty close. I bought this to replace a fan that came in my Wesena ITX1 HTPC case. I thought that the Wesena fan would be junk, but it was actually pretty good and close to silent. The thing I didnt like about it, though, is that it was barely moving any air.

> 24 hourUsed this to replace the extruder fan on my monoprice v2. its basically silent vs the rather loud fan the printer ships with.

> 24 hourI used this fan to replace the stock hot end fan. Works better than the broken one.

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.
