> 3 dayWhat can I say... Noctua is easily one of the best fan manufacturers around. Period. Ive been using their fans for years without a single issue. For a few extra dollars compared to the other choices, they cannot be beat in my opinion! This was used as a direct replacement for the failing CPU fan on a generic PC at work. I dont know the specs of the 40x10mm that it replaced, but the PC now seems to be running smoother. I suspect that the stock fan was not moving enough air, even before beginning to fail.

> 3 dayWell I bought this little guy to go on my keychain, but of course in Noctua fashion I was super impressed with the quality when I opened it, almost felt bad cutting the power cable off to use on my keychain. Quality fan if you need something super small.

> 3 dayReally quiet. Not sure why they need to be so expensive though. Works for what I needed them for

> 3 dayAlthough I really like these fans and they are quiet I feel like they have far too much packaging and come with too many accessories.
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.
