30-10-2024I use this fan on my 3D printer. I needed a quiet fan to keep the extruder cool. It works very well and is extremely quiet! Sometimes I have to check if the fan is running because its so quiet!

> 3 dayThese fans are awesome wisper quite compared to stock Monoprice plus fans that really were noisy and vibrated a lot the new fans are really quiet I like them alot. I recommend adding these fans to your Monoprice plus printer they fit perfectly as well

> 3 dayIm using this in my UPS as the original fan has always been bugging me in the background but this is a beauty yes you can hear it but you have to listen for the hum rather than it be there

> 3 daySwapped out the 30mm fan on my Prusa MK2s for this fan. It cuts down the noise by a LOT, so totally worth it.

> 3 dayI needed a fan to replace the noisy one on a micro ITX system with the AMD Hudson chip. Perfect fit, zero noise, great airflow. A bit expensive for such a small fan but it is a real ball bearing fan with a very high quality feel to it. It comes with a large selection of connectors and adapters and both screws and rubber standoffs for mounting. If you need a 40MM fan and noise is an issue this is the one you want.

> 3 dayThis was perfect for modding my Western Digital TV Live. Nice clean hardware, lots of choices. Good buy.
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.
