Product description

The NF-A4x10 24V PWM is a PWM-enabled 24V variant of Noctua’s award-winning, premium-quality NF-A4x10 40mm fan. As such, it is ideal for 24V-based 3D printers as well as various other 24V applications. Featuring an AAO (Advanced Acoustic Optimisation) standard frame and sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A4x10 is renowned for its superior performance and outstanding quietness of operation. Smooth Commutation Drive technology and Noctua’s reference class SSO2 bearing ensure superb running smoothness and excellent long-term stability. Topped off with the included OmniJoin adaptor set, NA-AC9 adaptor cable for popular 3D printers (e.g. Creality Ender 3 & CR-10, Anycubic Mega), and Low-Noise Adaptor, the NF-A4x10 24V PWM is a premium choice for demanding 24V applications with or without PWM control.

24V PWM version

24V fans are used in various devices and applications ranging from 3D printers to automotive. With the included OmniJoin adaptor set, the NF-A4x10 24V is a proven, PWM-enabled premium solution that gives you full flexibility both for replacing existing 24V fans and for new, custom applications.

Please Note: Being a 24V fan, the NF-A4x10 24V cannot be run at 12V and requires a starting voltage of at least 17V. It is therefore not suitable for standard PC applications.

Flow Acceleration Channels

The 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 Bearing

The 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.

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.

Ideal for 3D printers

Many 3D printers such as the popular Creality Ender 3 or Anycubic Mega use 24V fans. With the included NA-AC9 adaptor cable for JST XHP-2 2.5mm headers as well as the OmniJoin adaptor set that makes fitting custom connectors a breeze, the NF-A4x10 24V PWM is an ideal choice for cooling the hot end of 24V-based 3D printers or for additional part cooling.

Please Note:

Being a 24V fan, the NF-A4x10 24V cannot be run at 12V and requires a starting voltage of at least 17V. It is therefore not suitable for standard PC applications.
