> 3 dayBeh...che dire....qualità noctua. impressionante come una ventola così piccola sia così bella. unica nota negativa è il flusso daria, molto silenziona ma pensavo un flusso maggiore

> 3 dayIch habe den Lüfter als Upgrade für meinen Anycubic i3 Mega S gekauft und bereue dies kein bisschen. Mit neuen Treibern und den Lüfter ist der Drucker sehr Leise geworden und kühlt meiner Meinung nach auch ein bisschen besser als der Standardlüfter. Hier macht sich die Qualität sehr bemerkbar.

> 3 dayGood option for Hikvision NVR. Quietens it down but not completely, you’ll still not want it sat on a shelf next to where you sit unless background noise is your thing. Quieter than stock tho

> 3 dayI used 2 of these fans in a 1U sized Atom based Firewall/UTM, (Untangle 11), thats located where it needs to be as quiet as possible. They work perfectly, nice and cool and I barely hear any noise. Excellent!!

> 3 dayMade my 3d printer quieter. Maybe Ill get a larger size for my printers PSU.

> 3 dayPurchase another brand sometime ago and it claimed to have 27db but was loud, I can hear the fan about 30 feet away. This one is 17.9db and it is about 10 times more quiet. I have to put my ear next to the fan to hear anything. The air volume however is about half of my old one but that was still adequate for cooling. I dont think this thing even has 17.9db and my old one probably a lot more than 27db. It comes with all kinds of adapter and I did not even have to do any soldering to convert from 3 pin to 2. The instruction is also very clear. I purchased another one immediately to finish my project, highly recommend it.

> 3 daySuper quiet. Used these to replace the hotend fan on my printer, and for a cooling fan for my pi. Both were super easy to install and the extra connectors that come with them make different systems really compatible.

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.
