> 24 hourI didnt think a fan this small spinning at 4500 to 5000 RPMs could be so quiet.

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

> 24 hourTried others but they started making noise or failed outright. This one lasts and stays very quiet.

> 24 hourCome sempre si confermano le ventole più silenziosi che ci siano sul mercato.. Possono costare quelle 5 o 10 euro in più di altre ventole che assicurano la silenziosità.. Ma credetemi.. Solo loro effettuano un lavoro alla perfezione..

> 24 hourI bought this fan to replace one the same size on a brand new Swann home security recorder I just bought which was unbearably noisy. The fan arrived well packaged with comprehensive instructions in English and an array of adapters including optional extension cable, a noise reducing resistor cable to slow the fan down, 3 pin to 2 pin adapter, various plug types with cable connectors, new screws and rubber damping fixings. The fan I was replacing was running at 6000rpm which was ridiculously noisy. This fan is advertised at 4500rpm dropping to 3700rpm with the resistor cable. The slower the quieter! I was sceptical but delighted to find it works and at 3700rpm the noise level is much reduced making it possible to sleep in my spare room again. Only slight issue is the fixing holes were bigger that those on my old fan. So I had to carefully widen the holes on my aluminium mounting brackets by gently reaming the self tapping screws in and out a couple of times. Delighted I now have a quiet fan on my device.
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.
