> 3 dayI purchased this 12v 40mm x 10mm fan to replace a 40mm x 20mm fan that was in a very expensive Auto/RV/Watercraft battery charger/tender. The original fan was EXTREMELY noisy, and made my garage unpleasant to be in. This new fan is near silent, and moves more air than the original fan did. The fan comes with a 3-pin connector, and my battery charger/tender circuit board was a 2-pin, but this package comes with a number of converters - one being a 2-pin. Took me minutes to install, and I saved a lot of money from having to buy a new battery charger/tender. The pin setup was correct the first time - I know there are reviews that say the polarity is backwards, but this one worked right out of the box. An absolute must buy!!

> 3 dayQuiet, small, I assume it will be reliable as well.

> 3 dayDer Lüfter ist gut, benutze ihn für meinen Anycubic Mega Pro, aber er ist lauter als gedacht. Habe für mein Netzteil ein billigeres Produkt gekauft, das Leiser ist. Aber das Zubehör von Noctua, sowie die Hochwertige Verpackung ist ein Super! Sehr viel Zubehör, man muss gar nicht mal Löten.

> 3 dayHabe mittlerweile mehrere davon in meinem Drucker verbaut. Lüfter kommt mit viel Zubehör, lässt sich leicht verbauen und hat genug Kabel dabei. noch nie einen leiseren Lüfter gesehen.

Greater than one weekWie erwartet sehr leise. Teilweise vergesse ich meinen 3d-Drucker aus zu machen, weil im standby nicht mehr hörbar ist. Leider liegt kein passendes Adapterkabel mit den richtigen Anschlüssen bei. Aber das ist leicht um zu basteln.

> 3 dayI needed to replace a fan in a dual drive enclosure. This was exactly what I needed and it is extremely quiet.
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.
