> 24 hourNoctua fans have always been perfect, and this one is no exception! I love it and it sooo much quieter than my stock 40mm fan!

> 24 hourReplacing OEM CPU fan from a Synology Diskstation DS411+ NAS. Fits great. Connection to motherboard was a little finicky. Luckily, the fan kit includes a generic adapter that just has black and red wires coming out, as well as wire connectors. I cut the wires off the stock fan, stripped the sheathing off. Stripped the sheathing off the Noctua adapter. Joined in the wire connector - easily done by clamping down with a pair of pliers. The waterproof goop also extrudes out into the wire cavity to protect them even more!

> 24 hourThis might seem expensive for a little fan, but noctua is always the best when it comes to being quiet. Ive bought a bunch for my pc and I love them.

> 24 hourEine hohe Vielfalt an mitgelieferten Adaptern und Verbinden ermöglicht es diesen Lüfter fast überall zu verwenden. Es wurde sogar darauf geachtet das die Stromdiebe mit Fett gefüllt sind um eine Korrosion der Leitungen zu verhindern! Getoppt wird das ganze noch durch eine sehr hochwertige Verpackung! Bei mir läuft er seit nun fast 1,5 Monaten 24/7 um meinen Raspi 4 zu kühlen, da der Hersteller eine Garantie von 6 Jahren gibt, ist wie zu erwarten noch keine Veränderung der Lautstärke o. ä. festzustellen.
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.
