Greater than one weekPrima leiser Lüfter. Als Hotendlüfter für 3D Drucker leider nicht zu gebrauchen wegen zu geringem Luftdurchsatz. Ich habe es ausprobiert, das Hotend war nach Einbau des Lüfters dauernd verstopft. Austausch gegen den lauten original Lüfter behob das Problem sofort.

Greater than one weekI used this to replace a prior fan on my 3d printer. This fan is VERY quiet in comparison and seems to have enough air flow. I did have trouble with the connectors that Noctua sent. The previous connector just had a long wire. Noctua includes an adapter kit with connectors to electrically connect 2-3 wires. The connectors werent grabbing and holding, so I eventually just snipped the wires and soldered them in with no problems.

24-09-2024I have had a series of problems with a Migbot 3D printer. The original 40mm fan that cooled the filament feed section failed and ruined the printed parts of the filament feeder. The original fan was noisy! I replaced it with this fan and what a difference - total silence - such a relief.

> 3 dayReplaced the fans in my security DVR. Even though it was built into the wall, you could hear the fans humming through out the basement. Now it’s nothing but silence.

> 3 dayNice and quiet. Came packaged nicely with all necessary connecters needed. They move a descent amount of air for my parts cooling fans on my FT-5 printer.

> 3 dayIch habe den Lüfter am Hot End meines Anycubic i3 Mega verbaut. Der ist kaum noch hörbar. Tolles Produkt. Absolute Kaufempfehlung. Nach der zusätzlichen Installation von TMC2208 Stepper Treibern hört man jetzt nur noch die Lüfter von Netzteil und Mainboard. Das ist gut zu ertragen ... wird aber demnächst auch noch geändert.

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.
