SUNON KDE2404PFVX 24V DC Brushless Inverter Fan 4010 4cm x 4cm Ultra-Quiet Cooling Fan for PC Radiators and Multi-Platform Heat Sinks Brand New Original 2-Wire or 3-Wire Model
SUNON KDE2404PFVX 24V 1.9W 4cm Ultra-Quiet Inverter Fan for Radiator Cooling

Designed for targeted thermal management, the SUNON KDE2404PFVX is a compact 4cm x 4cm brushless DC inverter fan built to SUNON's manufacturing standards. Operating at 24V with a 1.9W power draw, it delivers focused airflow to cool components attached to radiators and multi-platform heat sinks. Its primary design advantage is ultra-quiet operation, making it a practical choice for home theatre PCs, quiet office workstations, or any enclosure where minimising acoustic disturbance is a priority. Supplied brand new as an original SUNON component, it ensures compatibility and performance as specified by the manufacturer.
Features and Construction

This fan integrates several design elements aimed at reliable, quiet cooling in compact spaces. Its construction follows SUNON's build standard, focusing on consistent performance for heat dissipation applications.
Material and Build
The fan utilises a brushless DC inverter motor, a design known for its reliability and reduced electrical noise compared to brushed alternatives. The plastic impeller and housing are engineered for balanced rotation at the specified voltage, contributing to the low-noise profile. As a brand new original component, it meets the material and tolerance specifications set by SUNON for the KDE2404PFVX model, ensuring it performs as intended for radiator cooling tasks.
Size and Practical Fit
With dimensions of 4cm by 4cm (often referred to as a 4010 size), this fan is designed for installations where space is at a premium. It fits standard mounting holes for 40mm fans. The supplied 15cm wire, available in either a 2-wire or 3-wire configuration, provides sufficient length for routing to a power source within a typical chassis or enclosed system, offering flexibility during installation.
Uses and Placement

The KDE2404PFVX is designated for use with multi-platform radiators, indicating its versatility across different cooling system designs. Its application is centred on moving air through heat sink fins to transfer heat away from electronic components.
Event or Professional Use
In professional or dedicated computing environments, such as servers, networking equipment, or point-of-sale terminals with limited ventilation, this 24V fan can provide essential spot cooling for specific hotspots. Its ultra-quiet specification is less critical here than its reliable 24V operation, which is common in many industrial and embedded systems, ensuring compatibility without requiring voltage regulation.
Everyday Home Use
For everyday home computing, this fan is ideal for small form factor (SFF) PCs, compact media centres, or as supplemental cooling for a graphics card or chipset heat sink. The quiet operation prevents it from becoming a distracting noise source in a living room or bedroom setting, while its small size allows it to be fitted into tight spaces within a PC case that larger fans cannot occupy.
Benefits and Buying Value

The value of this fan lies in its specific combination of size, voltage, and acoustic performance. It addresses a clear need for effective, quiet cooling in confined spaces without requiring modification or voltage conversion.
Reuse and Low Maintenance
As a brushless fan, it requires no end-user maintenance. The design has fewer wearable parts than brushed motors, supporting longer service life under normal operating conditions. Its standard 4cm form factor means it can be reused in future projects or as a replacement in other compatible equipment, providing value beyond a single installation.
Why Choose This Product
Choose the SUNON KDE2404PFVX when you need a guaranteed original 24V cooling fan from a recognised manufacturer (SUNON) for a radiator or heat sink. Its key differentiators are its specific 4cm size for compact spots, its 24V operation for direct compatibility with many systems, and its design for ultra-quiet performance. The option between 2-wire and 3-wire models allows you to select the correct connector for your existing header, simplifying the installation process.
