> 3 dayI picked up a new (used) mobile VHF/UHF radio for satellite work and was surprised at how noisy the stock fan was. This was a great replacement option. The fan comes with a lot of different connectors that would be appropriate for PC applications, but for the radio, I simply spliced wires and reused the existing connector, using heat-shrink tubing to keep it taut. Its much quieter now.

> 3 dayVery disappointed. I ordered two of these fans. One was new as expected, the other is used and abused. Looks like it was running for awhile before being returned rather worse for wear.

> 3 dayBruit quasiment inexistant et pour cause, il est très peu puissant, le flux dair est beaucoup trop faible. Ne convient pas pour refroidir une hotend par exemple. Mais très bien pour les cas ou un gros débit nest pas nécessaire. Le packaging est (comme critiqué par beaucoup de personnes ) exagéré.

19-11-2024Bei mir kommt der kleine Noctua in einem Asus Sabertooth z77 als intakte Fan für den Thermal Armor zum Einsatz. Nach 6,5 ans hat sich mein alter Noise Blocker mx1 in den verdienten Ruhestand begeben.

> 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.

Greater than one weekIt is SO CUTE my TUF mainboard came with this hidden little space for this baby fan to hide in it keeps the bits cool.
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.
