> 3 dayI ordered 2 of these fans for my Coralife aquarium light. The 3 pin to 2 pin adapter worked, though I did have to remove a tab on the 2 pin connector. Even having 2 of these fans operating at the same time is quiet. They seem to move about the same amount of air as the OEM fans, without all the noise. I would highly recommend them in any application that requires a quiet and efficient fan.

29-09-2024Ive been a massive fan (haha, get it? /s) of Noctuas for many years. And their fans continue to amaze me. This fan is no exception.

> 3 dayNeeded a replacement fan for a security camera base unit and this one did the job perfectly. The included rubbery clips and offsets allowed for a good fit. This fan is quieter than the original fan that came with the equipment (and eventually b failed). Been running perfectly and quietly for over a year now.

> 3 dayUsed this to replace my Ender 3 hotend fan as the original one was extremely loud, I did notice quite a difference when switching to the Noctua as it was much quieter.

26-09-2024Wie 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 purchased a Sannce 16CH AHD 720P HD Security Camera System with 8x 720P 1.0MP Superior Night Vision CCTV Cameras (P2P Technology, Motion Detection & Alarm Push, Vandal and Weather-Proof Body). The fan installed was VERY loud. Read the reviews and tried this one out. I would guess it reduced the noise by 75%. You can still hear it, but its not waking up my dogs. The rubber screws worked really well.

> 3 dayAcheté 2 ventilateurs Noctua pour remplacé les 2 ventilos de mon imprimante 3D. Ils font le même job avec un niveau de bruit très inferieurs aux originaux. Très bonne qualité de fabrications et plusieurs adaptateurs fournis, très pratique dans mon cas, mais pas forcement utiles pour tout le monde

> 3 dayDer 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.
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.
