> 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 dayI bought these fans to replace some noisy fans in my sisters DVR. These fans are VERY quiet and the move as much or more air then the original fans. When these arrived I was surprised to see how nice the packaging was and they provide several different connectors to allow you to connect them to just about anything. I will definitely buy these again the next time I need super quiet fans.

> 3 dayI bought this fan to install on my 3d printer. It is nice because i have it wired with the plug so i can quickly disconnect it when needed. It is very quiet and provides adequate cooling.

> 3 dayThe fan in my TYT was VERY noisy, and it finally went out. I replaced it with this fan which was the same air flow. As advertised, it is ultra quiet. I had to look to see if it was actually moving.

> 3 dayThis is a great fan to place in small htpc cases. Despite the small size (small fans are usually very loud), it is so quiet, its hard to tell if the htpc is even on.

> 3 dayWell, this brand exudes quality and the included mounting hardware and conversion cables are impressive. Dont want your electronics to die prematurely? Trust Noctua, not no-name brushless fans. The only minor thing is that it is not as whisper quiet as people make it out to be. I can definitely hear it in the same room 6 ft away, but its not bothersome, more like a very low white noise.
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.
