    Whisper quiet and the perfect replacement for the junk fans that ship with most 3d printers. I particularly appreciate the fact that the packaging comes with a number of different electrical connectors allowing maximum connection flexibility.

    Ventiladores que cumplen lo que dicen, buena ventilacion y un nivel de ruido muy bajo

    Needed a replacement fan for a security camera base unit and this one did the job perfectly. The included rubbery clips and offsets allowed for a good fit. This fan is quieter than the original fan that came with the equipment (and eventually b failed). Been running perfectly and quietly for over a year now.

    it is different than other 40mm fan, silent.

    I have to admit...I was very skeptical. After listening to my cooling fan for a few months Id had enough.

    I bought this to replace a loud fan for my 3d printer head. This fan really cut down the sound. The only thing I did not like about it, is with all the adapters, it did not come with the small type I needed so I had to cut the plug off the old fan and solder it to this new fan.

    Lo compre para sustituir otro ventilador que era ruidoso pero es que este es igual por no decir peor.Ni con el cable para reducir la velocidad a 3700 deja de ser ruidoso.lo he bajado a 2500 rpm y ya casi no se escucha pero claro ya no refrigera tanto y en verano lo subo a tope por lo que pueda pasar.

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 Channels

The 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 Bearing

The 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 Pads

Integrated 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 Microstructures

With 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.
