> 24 hourEverything the 5 star reviews said is true. I purchased this fan to replace a cheap stock fan that was noisy. Perfect drop in replacement.. And with the SSO-Bearing... it will stay that way for years! WIN WIN.

> 24 hourI bought this fan to replace a CPU fan in a bookshelf computer that was being used as a router box. The stock fan I got with the computer was extremely loud even during a minimum of load.

> 24 hourAs shown in the pictures . That’s how I received the item. There are screw marks in the mounting holes. Possibly from someone using a screws that are too large . The box also have holes for I think 3 more of those brown flexible things. But only came with 1. Have not tested if the fan actually works

> 24 hourIch habe es in mein Ender 5 Pro verwendet/eingebaut (mit Externe Netzteil). Vergleich mit dem Original Lüfter was eingebaut ist wie Autobahn und Wald. Das Original Lüfter was eingebaut war misst der Schallpegelmesser 60-70db. Bei kurze Zeit ging noch aber wenn der 3D Drucker über 24h läuft ist es sehr nervig. Nach dem Einbau von Noctua, Schallpegelmesser misst nur noch maximal 40db und es ist sehr angenehm ins Ohren. Jetzt höre ich nur noch die Achsen von Drucker. Sein niedrige Geräusch ist nicht nur seine Leistung sondern auch wie es kühlt. Die genaue Kühlleistung kann ich leider nicht messen aber ich bin sehr zufrieden damit. Es ist wirklich ein Kaufempfehlung.
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.
