> 3 dayI have had this fan installed on a Cocoon Create 3d printer for several months now. It is virtually silent, leaving me completely satisfied.

> 3 dayNeeded a new fan for an older 1U SuperMicro server I have at home. I had it open for another reason a few days ago and discovered the fan had frozen solid. That was late on a Friday night over Memorial Day weekend. I found this one here and it was at my home by Sunday afternoon.

> 3 dayIts a nice fan with every kind of mount and wire harness you could need included in the package. The packaging is beyond 5 star. Ive bought expensive watches that werent packaged so nicely. That said I would have been just as happy with a plain box and $5 lower price.

Greater than one weekSwapped out the 30mm fan on my Prusa MK2s for this fan. It cuts down the noise by a LOT, so totally worth it.

> 3 dayUse this 40mm Noctua to replace a noisy fan with a blown-out bearing in a ZyXel USG router (of all things)... and walla: completely silent now. Ive only had limited experience with Noctua, but every time I order their stuff, they always seem to do the little things well - extra mounting parts included, luxurious packaging and solid build quality (even if it is with plastic and rubber), nice documentation, etc. I really appreciate companies who focus on doing a few select things really well, as opposed to trying to be everything to everyone, and Noctua appears to adhere to this paradigm very well. A+++

> 3 dayEin sehr leises Teil. Und die Qualität und das Zubehör sind auch TOP. Liegt wohl an der Verpackung :-)
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.
