> 3 dayGreat fan! I used it to replace the fan in the ouya I bought, way quieter than the original fan.

> 3 dayI got this to replace the crappy original XBox 1.0 GPU fan that was annoyingly loud since day 1. This was a literal drop-in replacement, as this fan happens to fit snugly into the recessed portion of the heat sink, requiring no screws or other fasteners. The fan is surprisingly quiet for its size, so much so that I wasnt even tempted to try one of the two included low-noise adapters. The fan also comes with an extension cable, long noise isolating rubber mounts, and even some tool-free wire joiners. Everything is high quality and good value for the sale price. I only wish I could have bought it 18 years ago.

> 3 dayI purchased this to replace a cheap 40mm fan for my extruder on my 3D printer. I cant even hear this fan, huge improvement over the stock fan. Also the adapters and cords it comes with are extremely useful so you can hook it up within seconds with minimal effort. Highly recommend to anyone who needs to replace their extruder cooling fan.

> 3 dayAllinizio ero preoccupato perché non sentendo alcun rumore credevo di averla collegata male, invece era funzionante ma impercettibile come rumore! Noctua è una garanzia!

> 3 dayAl mes de uso dejó de funcionar bien y el flujo del aire bajo a menos de la mitad. Al reclamarlo al vendedor, su solución es que abriera una incidencia en el servicio técnico...

Greater than one weekIch habe mit diesem Lüfter den lauten Standard-Lüfter ersetzt. Der Einbau gestaltet sich sehr einfach, nur der Stecker vom Noctua muss abgeschnitten und mit dem vom originalen Lüfter ersetzt werden.

Greater than one weekPurchased for replacement fan on Anet A8. Very quiet. Used the included Skotchlok connectors which made installation a breeze. A little more expensive but it was worth it to me.

Greater than one weekUltra silencieux, bon airflow, rien à redire
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.
