> 3 dayis well worth it. Replaced 40mm fan in ZyXEL NSA310. Zero hum or clicks at the same rpms. Id say it is solid replacement fan for any NAS requiring 40mm fan.

> 3 dayI installed this into the control box housing for a Railcore 3d printer. I had to use a 24vdc to12vdc step down but that was no issue. The fan was easy and quick to install. It fit my printed fan housing perfectly. More importantly, it is QUIET and the speed is variably adjusted from a sensor I installed and all is working perfectly and did I say, quietly?

> 3 dayGreat little fan! Fits on a MACCHIATObin if you slice off some plastic with a sharp knife.

> 3 dayThese Fans are fantastic. The performance is great, but where these fans really shine is in the packaging and with the add ons. The fans come packaged in a way that shows great attention to detail and care. They also come packaged with extras like rubber mounts and several wiring choices. The care shown in how these products are packaged and the extras that are included justify the price and instill a confidence in the brand.

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.
