17-11-2024Der Lüfter schafft für seinen Geräuschpegel gute Leistung, und hat die Lärmbelästigung am Hotend meines 3D-Druckers deutlich verringert. Irritierend war die übergroße Verpackung und viel zu viel mitgeliefertes Zubehör, was alles nicht gebraucht und somit entsorgt wird. Nachhaltig geht anders.

18-11-2024What can I say... Noctua is easily one of the best fan manufacturers around. Period. Ive been using their fans for years without a single issue. For a few extra dollars compared to the other choices, they cannot be beat in my opinion! This was used as a direct replacement for the failing CPU fan on a generic PC at work. I dont know the specs of the 40x10mm that it replaced, but the PC now seems to be running smoother. I suspect that the stock fan was not moving enough air, even before beginning to fail.

21-11-2024Der Lüfter ist wirklich ein Traum! Habe diesen im CR10 zum Kühlen des Extruders im Einsatz. Am Anfang dachte ich er läuft gar nicht, da er wirklich kaum bis gar nicht hörbar ist. So einen extrem leisen Kühler hatte ich noch selten gesehen, werde jetzt alle anderen 40x40mm Lüfter gegen diesen tauschen, das Zubehör dabei grandios, Scotch klemmen, Schraubenlose Montagemöglichkeiten für noch mehr Dämpfung, etliche Adapter, 1A!

Greater than one weekIch habe viele Lüfter getestet für meinen 3D Drucker entweder zu laut oder bereits nach wenigen Tagen defekt.

> 3 dayInstalled on a HBA card with a couple 4-40 screws into the heatsink, dropped temps a ton.
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.
