> 3 dayI upgraded the fans on my 3d printer and it came with everything I needed to install. It is soooo quiet now!

> 3 dayWould pay an extra $5 not to have the packaging. But wow, I didnt know a fan could be so quite. I am using it with an adapter on my Prusa Mk2, and its like an entirely different 3d printer. Very happy customer. If you need quiet, spend the money on a Noctua. You wont be disappointed. The flow is better than the stock fan as well.

> 3 dayInstallation went off without a hitch. Exceptionally well documented (in proper English, thats a major plus) and everything needed was in the package. More quiet than any other fan Ive used in the past.

> 3 dayNoctua stellt die besten Lüfter her. Ich bin noch nie enttäuscht worden. Sehr schön ist auch das Zubehör (Anti-Vibrations-Befestigungen, Lüfterschrauben, Low-Noise-Adapter, Verlängerungskabel und OmniJoin-Adapter für proprietäre Anschlüsse).

> 3 dayIch habe zwei von diesen Lüftern in meinem i3 Mega S verbaut, einmal am Hotend und einen für die Kühlung der Motortreiber. Super Leistung bei geringer Lautstärke, nicht zu vergleichen mit den originalen Lüftern.

> 3 dayReplaced an old fan in one of my rack UPS, ramps up properly and is about 10 times quieter than the stock fan while moving seemingly the same amount of air!
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.
