Featuring a max speed of 5000 RPM, ultra-quiet 19.6 dB noise level, and advanced PWM control, it delivers efficient, adaptive cooling. Its compact design with Flow Acceleration Channels and SSO2 bearing guarantees superior airflow, durability, and whisper-quiet operation. Complete with versatile adaptor sets, it’s the go-to upgrade for professionals seeking enhanced print quality and a quieter workspace.

## Description

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.

Review: Exceptional Replacement Fan for Ender 5 S1 3D Printer - I recently upgraded my Ender 5 S1 3D printer by replacing the stock fan with the Noctua NF-A4x10 24V PWM 40mm Fan, and the improvement has been remarkable. ✔️ What I Appreciate: Superior Quietness: The Noctua fan operates with minimal noise, significantly quieter than the original stock fan. This enhancement has made my printing environment much more pleasant. Efficient Cooling Performance: Despite its quiet operation, the fan provides excellent airflow, effectively maintaining optimal temperatures during extended printing sessions. High-Quality Build: The fan's construction is robust and durable, reflecting Noctua's reputation for premium quality components. PWM Control: The PWM feature allows for precise speed control, enabling the fan to adjust its performance based on the printer's cooling needs, which contributes to both efficiency and longevity. ❌ Areas for Improvement: Installation Considerations: While the fan itself is top-notch, users should ensure compatibility with their specific printer model. In some cases, slight modifications or additional adapters may be necessary for installation. 💡 Final Thoughts: The Noctua NF-A4x10 24V PWM 40mm Fan is an outstanding upgrade for the Ender 5 S1 3D printer. Its quiet operation, efficient cooling, and high-quality construction make it a worthwhile investment for those looking to enhance their 3D printing experience. ✔ Best For: 3D printing enthusiasts seeking a quieter and more efficient cooling solution for their printers. ❌ Not Ideal For: Users who prefer plug-and-play solutions without any need for modifications. 👉 Overall: 5/5 – An excellent fan that delivers on performance and quietness, significantly improving the 3D printing environment.
Review: Standard qualty that I've come to expect from Noctua, i.e. second to none. - There is something about Notcua fans that scream quality to me. This one is going in my Ender 3 as a hotend cooling fan, as I'm not sure if the existing one is working right or not. Although I'm not using the PWM, or Tacho Signals at the moment, there is room to be able to add something into the mix to allow me to see what the fans RPM is, or even to control the speed - though I'm unlikely to run at anything short of 100%. Actually, I love that the fan is extremely quiet at full speed.

### ⭐⭐⭐⭐⭐ Easy Swap, Quieter Tha Stock
*by V***O on 10 February 2026*

Installed on a Creality Ender-2 Pro. Like-for-like swap and super easy to install with the included OmniJoin adapters. I didn't use the included low noise adaper as it's already quieter than the stock fan.
