> 3 dayAmazing fan, has significantly quietened my wanhao duplicator i3+. The kit includes everything you need to plug it directly into your printer, but for neatness I trimmed the wires down, clipped the yellow wire off (for pwm - not needed on most printers), and re-crimped it to plug in directly to the hotend via a step-down voltage converter. It does move less air than the standard fan, so Im running it at 14 Volts, and it remains silent whilst pushing more air than the stock fan.

> 3 dayWhisper quiet! Highly recommended. Replaced the fans in the Ubiquiti USG Pro with these and we can actually sleep at night. The temp change is actually lower than before.

Greater than one weekWhile the color is uniquely identifiable, and I wish it was in simple black, I cannot deny it is whisper quiet and made a big difference for my Monoprice Maker Select V2 3D printer

> 3 dayThe fans are quiet on the highest setting. I have them attached to my playstation in the living room, and you cannot hear them untill you are within 2ft of them. great product and worth the money.

Greater than one weekWant to know how these are so quiet? They move virtually no air. Versus your average $.50 part fan, these move MAYBE half the volume? Probably less.

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.
