Greater than one weekWorks great for ender 3 v2 motherboard fan replacement. You’ll need a buck converter to get the 24v down to 12v but it’s worth it. It’s super quiet. The crimp connectors that came with the fans are very nice. Overall these fans are great and they work great in 3D printers.

> 3 dayFor this low price I expected something as cheap as the junk fan I’m replacing. This fan is high quality and comes with a complete set of adapter cables and installation hardware including silicon anti vibration stand-offs.

> 3 dayHikvision default fan was so loud that i could hear it upstairs in bed. Noctua fan was easy to install for an amateur like me. I used the rubber mounts instead of the screws (a must!) from 49-50db measured with an iPhone on top of the Dvr, down to 40-41db. A noticeable difference as I can barely hear it when I leave the room, let alone upstairs. Well worth it for peace in the house

> 3 dayYou know, its very hard to judge the size of some of these products on a mail order site like Amazon and so I thought I was getting a larger fan that the one I received BUT, having said that, this little fan fits very nicely right where I wanted it - blowing across my SSD. Using Crystal Diskmark, I was getting pretty high temperatures on my SATA SSD (46 degrees C sometimes). I was like, No es bueno! So I wanted to get a small case fan for better overall case ventilation and when this little guy arrived I was a little disappointed. But I positioned the fan right next to the SSD and guess what; my temperatures are down and staying down. Its 39 degrees right now which is much better. Also, this is like a Cadillac fan, for real. Super high quality from what Im seeing.

> 3 dayI installed this on my ender 3v2s hot end and the noise came down a good amount definitely worth the investment.

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.
