> 3 dayIts all you would expect from noctua in terms of sound level, though it seems to have a little bit of a raised lip around the edge on the front and back, which made it very difficult to slide into a U shaped bracket for my 1u case. Still a very good fan and now my under-the-couch server is nearly silent.

> 3 dayNice quality which is often lacking in 40mm fans. Moves enough air but not loud at full speed. I am using these to push air out of that rear 5 wide grill area (right above he PCI slots) at the back of Sonata III cases. Now if someone would just make a nice duct that pull air up off of the PCI cards (they just dont exist - 3D printers will change this), wed have some really good cooling of PCI cards for cases of this type.

> 3 dayUnbelievable quality. The packaging is impressive to say the least, the product is extremely well made, and with no loss of attention to detail. This very may well be the highest quality fan out there, especially for the costs. Hard to believe they can deliver such a fine product for so cheap. 6 out of 5 stars imo

Greater than one weekI have got to say, these Noctua fans are amazing. I put 3 of them in a security System DVR that I have. The security system is a Lorex, and the factory fans are incredibly loud, and dont last. I kept having to send the DVRs back to Lorex for replacement, do to the cooling fans going out. Iam on my 4 th. DVR replacement. I finally got tired of sending them back, just for cooling fan problems. So, I took matters into my own hands. I researched cooling fans, and found the Noctua. Yes they are a little pricey, I think I gave around $50.00 on Amazon.com, for three. It was the best $50.00, I have spent. These fans are so quiet, compared to those crazy cheapies Lorex uses....If you are having cooling fan issues in your electronic devices, give Noctua a try, you will be amazed.

> 3 dayFan is nearly silent when on. I replaced the two fans in my ender 3 with these and the printer is barly noticeable when on. Worth double easily
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.
