> 3 dayStill strong and quiet, after months of constant use in a cramped enclosures with no real intake vents. Larger Noctua fans have worked very well for me, so I bought these expensive little suckers to replace the noisy stock fans in three

> 3 dayI normally dont write product reviews but every once in a while you run accross a product that represents excellence in every way. Ive purchased a Noctua CPU cooler that rivals water cooled performance years ago. Its still running perfectly. I needed a replacement fan for an NAS drive and consideredd several other product and figured I stick with Noctua for my replacement. If you need a fan or cpu cooler/fan(s) go with Noctua. You wont be dissapointed.

> 3 dayI use this fan on my Makerbot Replicator 2X because the stock fans melted... twice... this fan has lasted more than 5x as long as the original fans and is still going strong.

> 3 dayAvevo un minipc con J3455 in case LC-Power LC-1350MI a dissipazione passiva, sotto carichi leggeri arrivava a 65-70 gradi, niente di grave, ma non mi piaceva comunque.

> 3 dayArrivato con tensione sbagliata. Non mi sono accorto subito ed istallato sotto 24 volt si è bruciato. L’ho buttato in pattumiera.
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.
