> 3 dayThis fan is an excellent replacement for the noisy fans from my qnap ts809pro power supply. Together with the NF-a4*20mm FLX 40 mm. First the first time i only hear the hard disks.

> 3 dayBought this for my hotend on my 3d printer. Installed easy and the sound is almost non existent. Fanstastic packageing and 2 day freight, I will buy another for the cooling portion of my 3d printer.

> 3 dayIch habe den Lüfter an meinem 3D-Drucker in Betrieb um das Board zu kühlen, wenn der Drucker nicht in Betrieb ist, der Lüfter aber trotzdem läuft ist er auch bei 12V nicht störend.

Greater than one weekInsanely quite! My 3d printer is now near silent when in idle.

> 3 dayAdded 4 of these to my CR10-S pro printer. They replaced all the stock coolers other than part cooling fans. Need to downstwpcthe voltage 24V to 12V, they exceed my expectations in noise and in how hey look, literally packaged with everything you could need for a variety of installations.

> 3 dayI bought a motherboard that used a 30mm fan to cool the chip set but came with a mount for a 40mm. After changing out some of the case fans for Noctua quiet fans I could still hear the little 30 mm fan screaming at me; so I bought this one and the silence is wonderful
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.
