> 3 dayHabe diesen Lüfter auf meinem Anycubic I3 Mega 3D Drucker als Hotendlüfter und Teilelüfter verbaut. Er hat den Geräuschpagel des Druckers signifikant gesenkt. Qualitativ konnten keine Mängel festgestellt werden und der Transport war auch in Ordnung.

> 3 dayYou might be using this for something different, but I got sold on it as a recommendation for modding my Dreamcast heat througput and noisy as hell fans. Needless to say, this is one of the better alternatives out there. Superior cooling and you can barely hear it. Perfect for modding the DC!

26-09-2024Bought this fan kit as a replacement for my Reolink NVR which records images 24/7 from the CCTV cameras. The NVR fan was noisy within the home and I couldnt relocate it anywhere else easily. So replacement fan kit was the answer. Before ordering I checked the fan size was correct with current fan. When fan kit arrived, power off my NVR, unplug all leads, open case and then remove the old fan (two machine screws and nuts), and fit new fan as direct replacement so same screws into same holes. For the electrical connections the fan is three contacts in the block, and the connector on the circuit board was two, so used the 3 to 2 adapter included. I also used the quiet fan adapter too, which i assume reduces voltage to reduce fan speed. Then tested to check working electrically and refit all camera cables etc. Probably the only 5 minute job I have done in a while, didnt bother reading instructions. For me this was a straight replacement item, so really easy. Immediate difference in reduced fan noise.

> 3 dayThis fan is VERY quiet and performs well. It came with so many accessories and cables, many of which I needed to use for my 3D printer (that mini 2-pin connector was PERFECT for my Anet A8 mainboard). I also used the low noise adapter on a different fan. 10/10, would buy many times over.
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.
