> 24 hourUsed in a VIA Mini ITX system. Was practically silent, just when putting my ear over the case I was able to pick its noise.

> 24 hourDespués de varios meses de uso puedo asegurar que este tipo de ventilador y marca nada tienen que ver con los ventiladores convencionales. Con un uso continuo y permanente el ventilador sigue haciendo el mismo ruido que el primer dia y es inapreciable, con otros ventiladores de estos tamaños el problema de su mal centrado lo sufrimos al poco tiempo de uso, con Noctua nunca pasa.

> 24 hourMy HP computer requires this size fan to cool the processor, and the cheap onboard fan did not last long. I chose this fan as a replacement, and I have to say, I am quite impressed. It was easy to install, and comes with sound deadening plastic bolts. I chose not to use the bolts, and the fan is whisper quiet anyway, and works much better than its predecessor. There are comprehensive instructions, and the whole kit is sturdily packaged. Kudos to Noctua for putting so much thought into both the design and presentation of the item.

> 24 hourI use a few of these on my 3D printer, work great for that task. Push a ton of air for their tiny size, and super quiet. Whats hilarious is that Noctua packs these in their 120mm fan boxes, so you get these little baby fans with a TON of extra space for the plastic packaging inside to fill, lol. Came with some additional wiring adapters too, which is nice. Stepped down the regular 3 pin cable to a 2 pin that my printer needed. Overall, love them.

> 24 hourI tried both the 2 pin adapter and the Omnijoin Adapter to connect into the fan input of Silverstone SST-FX350 powersupply. Neither worked. I had to use the 3 pin extender cable, run it through the back of the power supply, and connect it to my motherboards case fan input. To make sure that it keeps up with temps on the power supply, I had to install additional temp/fan software. Not really ideal overall, I wish the 2-pin adapters had worked.

> 24 hourBuena calidad. Muy silencioso, pero me temo que dan menos caudal de aire que otros ventiladores del mismo tamaño.

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.
