> 3 dayI replaced the fans on 2 Ham Radio mobile units. These fans fit very well....provided increased airflow, and were not noisy!

> 3 dayIch habe den Lüfter als Ersatz für meinen 3D-Drucker gekauft. Der originale Lüfter hat Geräusche wie eine Flugzeugturbine gemacht und mit den Vibrationen jeden 2. Druck versaut. Mit dem OmniJoin Adapter musste ich bei der Montage nur den originalen Lüfter abklemmen die Kabel in den Adapter stecken und zudrücken. So ließ sich der Lüfter ohne komplette Demontage des Druckers, ohne Löten sogar ohne die Kabel abzuisolieren wechseln. Der Lüfter läuft seitdem sehr leise und erzeugt keine von mir wahrnehmbare Vibration.

> 3 dayReplaced the fans in my security DVR. Even though it was built into the wall, you could hear the fans humming through out the basement. Now it’s nothing but silence.
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.
