SUNON KDE2404PFVX 24V 1.9W 4CM Ultra-quiet Cooling Fan for Radiator Systems

The SUNON KDE2404PFVX is a 24V DC axial fan designed specifically for cooling multi-platform radiators and heat sinks. Operating at 1.9W, this 4cm (4010 size) fan provides efficient forced-air ventilation while maintaining an ultra-quiet acoustic profile, making it suitable for applications where noise reduction is important. Supplied as a brand new original component, it ensures compatibility and reliable performance aligned with SUNON's manufacturing standards. The unit features a 15cm wire for convenient electrical connection and is available in your choice of a 2-wire or 3-wire configuration, allowing selection based on whether a tachometer signal output is required for system monitoring.

Features and Construction

This cooling fan is built to SUNON's specifications for the KDE2404PFVX model. Its primary role is to move air across radiator fins to dissipate heat from electronic components or small systems.

Material and Build

The fan is listed as a 'brand new original' SUNON product. This denotes it is a genuine first-party component, not a refurbished or compatible unit, constructed from the materials and to the tolerances specified in the original design. This ensures predictable performance and fit for integration into systems designed for SUNON's 4010 series fans.

Size and Practical Fit

The fan has a 4cm frame size, corresponding to the common '4010' axial fan designation (40mm x 40mm x 10mm). This compact form factor is intended for direct mounting on correspondingly sized radiators or heat sinks. The included 15cm wire provides sufficient length for routing to a nearby power connector or control board, offering installation flexibility within a chassis or enclosure.

Uses and Placement

The product information specifies the 'applicable object' as a 'multi-platform radiator'. This defines its core use case: active cooling for radiator assemblies used across various hardware platforms.

Event or Professional Use

In professional or dedicated cooling setups, this fan can be integrated into custom liquid cooling rigs, electronic enclosures, or specialised equipment where a reliable, low-noise 24V fan of precise dimensions is required. Its status as a brand new original component is crucial for OEM repairs, prototyping, or system builds where part authenticity and specification compliance are non-negotiable.

Everyday Home Use

For home technology enthusiasts, this fan is suitable for cooling projects such as small-form-factor PCs, network attached storage (NAS) units, media servers, or 3D printer electronics where a 4cm fan is specified. Its ultra-quiet operation makes it a practical choice for devices located in living spaces or home offices.

Benefits and Buying Value

The value of this product lies in its specification-matched performance, authenticity, and the flexibility offered by the wire configuration choice.

Reuse and Low Maintenance

As a standardised 4cm axial fan, it can replace failed or noisy units in existing equipment that uses this form factor. Being a new, original part contributes to longevity and reduces the risk of premature failure compared to unofficial compatibles. Its simple brushless DC motor design requires no end-user maintenance.

Why Choose This Product

Choose the SUNON KDE2404PFVX when you need a verified original 24V 4cm fan for a radiator cooling application. The key decision point is selecting between the 2-wire (simple power) and 3-wire (power plus tachometer) variant to match your system's control capabilities. The combination of specified ultra-quiet operation, 1.9W low power draw, and a practical 15cm wire makes it a directly applicable solution for its intended cooling task.
