> 24 hourJavais fais confiance a Noctua sur ce coup, mais très décu, il a grillé quelques mois après son utilisation. Dégouté !

> 24 hourGuter Lüfter, im Normalbetrieb leise, auf voller Drehzahl aber recht laut. Ich nehme denen nicht ab das der Fan 45000 rpm schafft, warscheinlich nen Tippfehler, könnte aber auch eine Fälschung sein, Support ist kontaktiert.

> 24 hourLa calidad es brutal de buena, no hace ni un solo ruido, es increíble el silencio. Tras silencia la CR10 con la placa duet al final lo que molestaba era el ruido de los ventiladores y cambiando este de capa se hizo el silencio. Ideal para quien tenga impresoras en un piso y necesito hacer piezas d noche y no moleste a los vecinos. La única pega es que son muy caros, ynaunq haya otros más baratos el silencio no es total como este que es 100%

> 24 hourHabe diesen Lüfter als ersatz für die Originalen viel zu Lauten lüfter von meinem Anycubic Chiron gekauft, nach dem Umbau ist dieser Flüster leise. Perfekte Lüfter

> 24 hourI installed this onto my 3D printer since the cooling fan on extruded was too noisy and well I can’t even tell it’s running now.

> 24 hourUsed 2 to replace the OEM fans in an Icy Dock 4 x 2.5 sata mobile rack .. quiet and dont have to worry about replacing them for > 5 yrs ..

> 24 hourIts all you would expect from noctua in terms of sound level, though it seems to have a little bit of a raised lip around the edge on the front and back, which made it very difficult to slide into a U shaped bracket for my 1u case. Still a very good fan and now my under-the-couch server is nearly silent.
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.
