> 24 hourI bought two of these as you can see on the picture. One to cool the print and one for the heatsink on the hotend. You will need a 30mm -> 40mm adapter to install it on a e3d v6 clone but you can easily find one on thingiverse to print yourself. I had problem with the low noise adapter as it seemed to not cool the heatsink enough and I was getting heatcreep with PLA over 205C. Removed the adapter and now the problem is gone. The fan are still dead silent so im very happy with my purchase.

> 24 hourI see now what everyones raving about. Noise level is none over my entire rig. Bought these to install on a 3d printed pci mount to help divert air under my gpu. Temps dropped by 2c which isnt much but they look great

> 24 hourI have been looking for a solución to the very noise fans on my Dahua NVR.

> 24 hourWer Noctau kennt weiß, dass es sich in aller Regel um sehr gut verarbeitet und langlebige Lüfter handelt. Zumindest in dem ersten Punkt ist der NF-A4x10 FLX keine Ausnahme, die Langlebigkeit kann ich schlicht noch nicht bewerten, aber auch da wird meine Erwartungshaltung gewiss nicht enttäuscht.

> 24 hourHoly moly, was not expecting it to be so quiet. I can’t hear the thing. Used this on my 3d printer for cooling the hotend, the old 30mm fan was way to loud. The one drawback of this is to my highly calibrated hand (sarcasm) it doesn’t feel like it pushes the same amount of air through it.

> 24 hourOttimo prodotto,molto silenzioso e performante. Io lho montata su un dvr x tvcc per raffreddare la scheda madre. Non ho dato le 5 stelle rapporto qualità prezzo solo perché è molto cara rispetto alle altre. Ma ripeto super silenziosa e performante. (Piu che l originale)Ottima confezione con cavetti di adattamento supporti in gomma per evitare vibrazioni ecc. La consiglio sicuramente a chi vuole un prodotto duraturo e risolvere definitivamente il problema della rumorosità ed allungare la vita alle schede elettroniche

> 24 hourPurchased this fan to replace the stock 40mm fan on my Monoprice Maker Select v2 3D printer. (Wanhao i3 clone). It fits perfectly, significantly quieter, and far more sturdy. Ive hit the fan with my allen wrench multiple times and havent broken a blade yet.

> 24 hourDeux étoiles de moins en deux points :
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.
