> 24 hourI bought this to install in an overheating wireless router. The packaging was overkill and it was a bit more expensive than other fans, but it works beautifully and I cant hear it running at all.

> 24 hourWell, this brand exudes quality and the included mounting hardware and conversion cables are impressive. Dont want your electronics to die prematurely? Trust Noctua, not no-name brushless fans. The only minor thing is that it is not as whisper quiet as people make it out to be. I can definitely hear it in the same room 6 ft away, but its not bothersome, more like a very low white noise.

> 24 hourBought this as a replacement for my Maker Select v2 3d printer, thing is ultra quite, right next to it you cant hear it. No issues on mounting it, direct fit. Just watch you plug it in correctly as this its a 3 pin fan, and my printer is a 2 pin, no issues with that though.

> 24 hourIts a worlds difference from the stock fan my printer came with. So amazing how much sound one little fan can make. I may replace all electronic fans with Noctua fans. I love it so much since Im sensitive to sound.

> 24 hourIts 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.

> 24 hourHo acquistato due di queste ventole insieme ad una 60x25mm e ad alcuni stepdown. Lo scopo era quello di ridurre il rumore prodotto dalla mia Creality Ender 3 MAX e ci sono riuscite alla grande. Dopo 3 mesi nessun segno di cedimento.

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.
