> 3 dayI hooked these up to my 3d printer and had to check the LCD to see if the power was on. These things are quiet! I like that they included multiple connectors for just about every situation. Time will tell how cool these keep the stepper motors and the hot end, but for now, Im pleased with this purchase.

> 3 dayI was working on an ACER desktop. BIOS had SmartFan application. CPU was running at 94 degrees Celcius. Replaced the heat sink grease. Still hot CPU. Turned SmartFan off in BIOS. SmartFan no longer reduced the 5volt CPU fan speed, but it did turn off the CPU fan after some minutes. The CPU fan connector is 5volts, the case fan connector is 12volt. The solution - this 12volt fan mounted on the CPU heat sink and powered by the motherboard case fan connector. Case fan is not controlled by SmartFan app. With this 12volt fan the CPU is running at 47 degrees Celsius; same programs running in each test. And the fan is so quiet, you do not know it is running constantly.

> 3 dayVery impressive packaging which included an array of connection adapters. Pleased with the low noise level. The installation went well once I cut the wires off the Noctua fan and my existing fan and rejoined the existing fan connector to the Noctua. True, the fan could have been installed without doing so with the adapters provided, but in my case it would have left too much wire to be contained in a small space.

> 3 dayThis thing is amazing. If you listen closely and the room is quiet, there is a little sound, very little. It moves more air better than the cheap fans too. I added mine to a cooling duct for my Prusa 3D printer with an MK8 print head. It is fantastic. I had installed a cheap fan , but I could hear it over the printers step motors throughout my house. I will be replacing the OEM fan on the MK8 itself too.

> 3 dayIve been a long-time fan of Noctua as the quality shines through (color scheme is another topic). The NF-A4x10s were used to cool multiple HBAs, specifically 2x LSI 9300-8is which connect 16x Samsung 860 EVO SSDs (for virtualization storage).

> 3 dayHabe diesen Lüfter aufgrund diverser Bewertungen für das Hotend eines Anycubic i3 Mega S gekauft. Der Lüfter kommt zwar in einer pompösen Verpackung mit reichlich Zubehör ... nur leider ist das das einzige was ich positives berichten kann.

Greater than one weekcomo marca premium que es en ventiladores para informatica, no defraudan, la unica pega que le pondria, que es muy caro para el tamaño que tiene, y que es de 12V lo cual limita mucho segun el dispositivo donde lo vas a poner, por ejemplo, se puede poner en una raspberry pi, sin problemas, pero como es de 5V el giro es mucho mas lento de lo que deberia, y no dara el rendimiento optimo, para que funcione perfecto, hay que usarlo en tomas de corriente de 12V, y este tipo de ventiladores tan pequeños, deberian ser todos de 5V

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.
