> 3 dayI have the Ender 3 Pro 3d printer, and used this fan to replace the hot end fan. The original got noisier and whinier after about a year. Ive moved to a new apartment and now the printer has to be in the living room so Im working on an enclosure, but for now, I wanted to quiet that fan.

> 3 dayCant really say enough about this fan. Even if it does not pump as much air as others, its quality is unrivaled. 6 year warranty, in todays age its hard not to support one of the last companies that stand by there products. 6 years is as good as a new car warranty, and this is a $15 fan.

> 3 dayA tiny 40mm fan that works well comes with incredible amounts of cardboard and plastic packaging, I dont mind the price of the component but I do resent the almost criminal level of waste the product generates.

14-11-2024I installed this in my D-Bot 3D printer when I added a Duet WiFi controller. I printer a controller housing that needed two fans for cooling the stepper controllers. Even thought I shouldnt need the cooling for the lower amps I will be printing at, since it will be in an enclosed box, it cant hurt! It is very quiet, almost silent, and moves a good amount of air. I will purchase another one soon to replace the very loud hot-end fan.

> 3 dayAs shown in the pictures . That’s how I received the item. There are screw marks in the mounting holes. Possibly from someone using a screws that are too large . The box also have holes for I think 3 more of those brown flexible things. But only came with 1. Have not tested if the fan actually works

Greater than one weekLa ventola è stata acquistata per sostituire quella fastidiosissima di un registratore DVR per TVCC.
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.
