> 3 dayPutting the price aside as they are a primium price, these are great little fans. They come with everything you need to fit them to a pc and are as quiet as a fan gets

> 3 dayQuite simply, I will always buy this brand, they are built second to none and you cannot beat the noise levels! Getting the FLEX kit only reinforced the level of quality that goes into the product, when you see the number of applications one kit can have.

> 3 dayI ordered this to replace the extruder fan on my 3d printer. The one it came with moved a lot of air, but was a noisy piece of junk. This one seems to move ever so slightly less air, but its virtually silent. I really hesitated at the cost, but it was well worth it.

Greater than one weekIve now fitted two of these fans to my Ender 3 Pro - one for the hot end, and one for the motherboard. Its a bit inconvenient that the Ender 3 uses a 24v PSU, but with a buck converter to take the voltage down to 12v, this is a great mod for the printer that really reduces the noise over the factory fans.

> 3 dayYes! what you see on that picture is this fan attached to a 10G NIC with zipties!

> 3 dayWie in vielen Anleitungen im Internet, habe auch ich diese Lüfter hergenommen um meine 3D-Drucker leiser zu machen. Der Geräuschpegel wird merklich reduziert. Zumal diese Lüfter einen wesentlich höheren Durchsatz haben, wie die billigen Lüfter, welche original am Drucker verbaut sind. ich denke, das die Zuverlässigkeit auch wesentlich höher ist, wie bei den Originalen. Nicht auszudenken, wenn ein Lüfter während eines Drucks über Nacht ausfällt...

18-11-2024Replaced an old fan in one of my rack UPS, ramps up properly and is about 10 times quieter than the stock fan while moving seemingly the same amount of air!
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.
