> 3 dayreally really quiet but if you want to use these for 3D printing dont. they dont push quite enough air to cool parts. stick with the annoying loud fans sorry noctua love your fans.

> 3 dayI ordered two, one for a POI switch and one as a spare. The fan was nicely packaged and included a complete Installation kit including adapters for different connectors. The problem is that after a short time it stopped and would only run if given starting assistance. The second fan behaves the same - very disappointing!

Greater than one weekDie Dinger sind wirklich leise, aber auch wenig Luftdurchsatz.

> 3 dayLove the fact its so quiet, and came with a 3pin --> 2pin adaptor. Word to the wise - if youre using on a 3D printer then print out a fan cover asap. I managed to slice off a fingernail less than an hour after installing it while I was fiddling about rearranging wires :D Well worth the money.

> 3 dayReplaced the factory fan that came with my Reolink RLK8-410B2D2 NVR. The factory fan was so loud I got a headache if I was in the same room with it too long. This Noctua fan is whisper quiet.

Greater than one weekPerfection. What else would you expect.
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.
