> 3 dayThis fan is so quiet that, even at high speed, you think its not running. Used in Mega S 3D printhead. It got so quiet I was TRYING to hear it. It requires a little soldering skill (or you can use the included splicing kit). You can actually make it quieter, by slowing its speed...but why? Fantastic quality is obvious. Value for the money!

> 3 dayVery comprehensive selection of leads including (if all else fails) connections allowing you to re-use the existing connection if the supplied ones dont fit your purpose. In my opinion the product is over-packaged and a case of lets give it a smart package so as to help justify the premium price. The end result is lots of cardboard and plastic heading for the recycling bin. I have used Noctua fans before and I am sure that they are built with good quality components and certainly in PCs I have built they have performed well and silently. However I was using this 40mm fan to replace what I thought was a noisy fan in a Dahua NVR box. It was easy to switch over (I ended up cutting the supplied connection in half so as to not have to fiddle around with splicing the old connection on the new fan lead). The end result is just as noisy as the original ! Probably because there is no speed control in the NVR and the little fan just runs constantly at full speed. A small fan, running at full speed within a small enclosure is, (I now know) always going to be noisy however well made it is.

> 3 dayDieser Lüfter hat die absolute Laufruhe, ideal für den 3D Drucker. Er ist auch sehr leise, wenn der Lüfter läuft, muss ich schon hinschauen um zu sehen, daß er läuft.

Greater than one weekBest Fans every! So quiet and such good air flow!
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.
