> 24 hourThese little fans are absolutely amazing. I know many people have said this before but they are incredibly quiet even if you don’t use the special mounts that they come with. I had to do a double take and check it was actually working because I couldn’t hear anything.

> 24 hourLho acquistato per rimpiazzare la ventola della Anycubic Kossel, effettivamente non fa rumore, la stampante è dentro di un armadio per mantenere la temperatura costante, e il filamento non si è ancora bloccato nel hotend, che mi fa capire che rinfresca effettivamente il radiatore del hotend, detto ciò, la ventola soffia meno aria da quella originale, la scatola e gli adattatori è un piacere da vedere, ma sinceramente mi sembra eccessivo.

> 24 hourDropped in as a replacement for existing fan that had worn out and had increased noise.

> 24 hourDiese Lüftertypen laufen wirklich sehr, sehr leise. Habe diese kleinen Dinger gegen die Originallüfter aus einem Netzteil ersetzt. Und das schöne daran ist auch noch, dass verschiedene Kabelanschlüsse /Adapter mit dabei sind.

> 24 hourI ordered 2 of these fans for my Coralife aquarium light. The 3 pin to 2 pin adapter worked, though I did have to remove a tab on the 2 pin connector. Even having 2 of these fans operating at the same time is quiet. They seem to move about the same amount of air as the OEM fans, without all the noise. I would highly recommend them in any application that requires a quiet and efficient fan.

> 24 hourOmg, I have to look at my 3d printer to see if its on.. the fan is so quiet. very low flow but sitting next to the printer not printing I cannot even here this fan running...

> 24 hourI bought for my ender3. Wanted to do a fan design upgrade decided to upgrade the fan also. Installation was a little difficult but that’s because it’s a 12v and the power supply for the ender3 is 24v so I used a buck converter to step power down to 12v. It is quieter I can tell since I still have one of the stock fans on. I personally would recommend getting to since now I have to order another one. But I am glad I did purchase.

> 24 hourThis fan is extremely quiet and efficient. A little on the pricey side for the materials used
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.
