> 24 hourRunning via a buck converter, the cables, extension and adapter route perfectly. Genuinely quiet and a very significant upgrade.

> 24 hourIt is super quiet. Used to tone down the loud Unifi USG Pro

> 24 hourI bought this to replace a noisy hot-end fan in my Creality CR-10 3D printer (first gen). Its absolutely silent, you literally cannot hear it. However, the vibration pads near the screw holes make this thicker than an OEM fan, and it might not fit with your existing screws depending on application. The screws for this printer are M3 x 10 (0.5 pitch), and theyre not long enough once this fan is in place to secure it. You probably need M3 x 12, but the most accessible ones to me were M3 x 16, which I trimmed with a hacksaw to fit. Now its secure and silent as its ever been, very happy with this fan!

> 24 hourBei meinem Ubiquiti 500W PoE Switch und dem USG Pro Gateway war der WAF (WomanAcceptanceFactor) nicht sehr hoch. Die Dinger waren so laut, obwohl in einem Rittal Rack untergebracht. Lüfter getauscht, und siehe da: PERFEKT!!! Nur noch ein leises surren. Laut Controller Lüfterstufe bei 90% und Temperaturen nie über 60 Grad obwohl die beiden Geräte direkt untereinander verbaut sind und sich gegenseitig heizen.

> 24 hourIts every bit as good as advertised, but they under sell the adapter kit. This is so complete, and at a good price.

> 24 hourAvrei preferito meno fumo e più arrosto. Invece di una confezione così bella e completa, avrei preferito maggiori istruzioni in generale e delle istruzioni anche in italiano. Non si capisce che differenza cè tra il modello normale e il modello Flex; non è specificato a cosa serve il terzo filo (quello giallo); non è indicata la tensione minima di funzionamento. Né tali dati sono riportati sul sito del costruttore. E le istruzioni di montaggio sono sommarie. Ad esempio non è riportato quale dovrebbe essere il diametro del foro necessario per fissare i supporti in gomma che sostengono la ventola.

> 24 hourSo I purchase 2 of these to upgrade my Ender3. Was working great with stock hotend with Bowden Drive. However recently I purchased a all metal hotend and direct drive upgrade kit. Too Much Heat creep and stringing. I would suggest away from this fan if you are planning to change the hotend cooling fan. Rather get the NF-A4X20 FLX. Double the airflow helps with cooling during long prints.

> 24 hourDie Noctualüfter haben gemeinhin einen guten Ruf, zurecht.
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.
