> 24 hourHatte mir erhofft meinen lauten Lüfter am 3d drucker Hotend ein wenig leiser zu machen, was dieser Lüfter auch tut (so gut wie unhörbar) aber leider schaufelt der Noctua auch sehr sehr wenig luft im vergleich zum vorgerigen Lüfter mit gleichen abmessungen... das 2cm dicke Modell hätte bei mir leider nicht hingepasst und ich war schon auf etwas weniger Luft gefasst, aber so wenig?

> 24 hourThey guys do it right from the packaging to the adapters to the rubber mounting system. Its very well thought out. I used it to quiet down my Amcrest NVR, which sounding like a drone. A slight mode on the hole size on one bracket was all that was needed. Id say it dropped 20db.

> 24 hourPackaging great. Fans are almost silent. Replaced 28P Switch fans with these. Wow what a difference. Stock fans were like jet engines.

> 24 hourThese little fans are absolutely amazing. I know many people have said this before but they are incredibly quiet even if you don’t use the special mounts that they come with. I had to do a double take and check it was actually working because I couldn’t hear anything.

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.
