> 3 dayPurchased Noctua NF-A4x10 FLX fans for cooling DDR5 memory on Z690 platform. Made from high-quality materials, the NF-A4x10 is as quiet as it is efficient. Highly recommended!

> 3 dayArrivato con tensione sbagliata. Non mi sono accorto subito ed istallato sotto 24 volt si è bruciato. L’ho buttato in pattumiera.

> 3 dayCette appareil fait encore trop de bruit pour être situé dans un salon. Par contre, il fait un peu moins de bruit que le ventilateur précédent de mon NVR Hikvision DS-7608NI-K2_8P

> 3 dayI tried both the 2 pin adapter and the Omnijoin Adapter to connect into the fan input of Silverstone SST-FX350 powersupply. Neither worked. I had to use the 3 pin extender cable, run it through the back of the power supply, and connect it to my motherboards case fan input. To make sure that it keeps up with temps on the power supply, I had to install additional temp/fan software. Not really ideal overall, I wish the 2-pin adapters had worked.

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.
