> 3 dayè veramente silenziosa, alla massima velocità anche avvicinando lorecchio non si sente il ben che minimo rumore, in compenso produce poca aria, bisogna valutare di quanto flusso di aria si necessita

Greater than one weekI upgraded the fans on my 3d printer and it came with everything I needed to install. It is soooo quiet now!

> 3 dayCan’t beat the Noctua brand for quality. I’ve used these fans to replace the noisy ones that came stock on my Ender 3 3D printer. They run practically silently. Truly a huge difference. If you are planning on doing the same, remember they run on 12v and the ender 3 is supplying 24v from the power supply. a simple step down buck converter (which can also be found on amazon) will provide the right voltage for these fans to run directly off the power supply. The packaging and design is flawless. These are a premium product, with an exceptionally long warranty which is clear this company stands behind what they sell

Greater than one weekIf you’re using this for an ender 3 like I did, you will have to solder and use a buck converter to step down the 24v to 12v

> 3 dayCrazy quiet!!! I used them in a SG200-50P Cisco Switch (Redo the pin layout - Theres diagrams all over google). Dead silent. I sleep 10 feet away from them and there 4 of them on in the switch 24/7. Theyre crazy quiet, well worth the pretty penny.

> 3 dayInstalled in voxelab aquila 3d printer, needed 24v to 12v transformer obviously with this being 12v,fans amazing. All their products are.
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.
