> 3 dayI installed this fan underneath the PSU shroud in my case for a little extra cooling for my gpu. I didnt expect a big difference in temps but I thought it wouldnt hurt. Its maybe a 1-2° difference. I had a hard time installing it but only because my power supply is big and I had limited space. If you have a NZXT H210 and plan on doing something like this, Id recommend getting an SFX power supply.

> 3 dayGot some of these to quiet down a 3D printer. As with all of Noctuas products, theyre good quality and it shows, and theyre very quiet - plus these come with a bunch of useful parts like an extension cable, an adapter to lower the fans speed, wire splices, and other accessories, which was nice. I did find it was a bit weaker than the noisier 24V hot end cooling fan I was replacing with it, but I ended up giving it a little more than the rated voltage at about 12.75V and that gave it a bit more power, so it does its job while remaining whisper quiet.

> 3 dayExtremely quiet. I bought this to replace another 40x40x10mm fan that was super noisy, and it absolutely lives up to its description.

> 3 dayUsing as a replacement for the stock fan on a E3D Titan Aero. It is whisper quiet, very happy with this upgrade. No issues with heat creep.

Greater than one weekVery Quiet. Much more quiet than the fan it replaced. Better airflow.
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.
