> 3 dayI mounted them on my 3D printer and it is very quiet now, they were also easy to install with all the connectors they give you

> 3 dayThis fan is an excellent replacement for the noisy fans from my qnap ts809pro power supply. Together with the NF-a4*20mm FLX 40 mm. First the first time i only hear the hard disks.

Greater than one weekI picked this little guy up to use as an assist fan to cool the VRM on my ASUS TUF Mark 1 mobo. There is a built in spot for a 40mm fan on these boards and though probably not really necessary, I populated it anyway and I chose the Noctua because I wanted it to be quiet which, it is even at 3800 RPM, not a peep.

> 3 dayI bought two of these as you can see on the picture. One to cool the print and one for the heatsink on the hotend. You will need a 30mm -> 40mm adapter to install it on a e3d v6 clone but you can easily find one on thingiverse to print yourself. I had problem with the low noise adapter as it seemed to not cool the heatsink enough and I was getting heatcreep with PLA over 205C. Removed the adapter and now the problem is gone. The fan are still dead silent so im very happy with my purchase.

Greater than one weekAcquistata per sostituire la ventola della mia stampante 3D sono rimasto impressionato della qualità del prodotto e della dotazione di accessori al di la di ogni aspettativa. La ventola si presenta in una confezione che la protegge dagli urti, forse anche esagerata. Tra gli accessori ci sono cavetti di prolunga, un adattatore universale, un cavo di riduzione del numero di giri e quattro elementi di fissaggio in gomma. Ho montato la ventola senza i quattro supporti in gomma, con le viti originali della stampante ed il risultato è stato oltre le aspettative. E talmente silenziosa che non la sento girare e a volte devo guardare bene per capire se sta funzionando... Per quanto riguarda il flusso daria credo che sia più che sufficiente in quanto lestrusore non si è mai bloccato da quando la ho montata.
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.
