Coldplate Alphacool 13891 Acrylic Transparent 125x480x42mm RGB 5V

The Alphacool coldplate with transparent acrylic housing measures 125x480x42 mm and integrates 5V RGB illumination for visual customization. Designed for use in computer cooling assemblies, the coldplate provides a flat, machined surface and a clear top to monitor coolant flow and internal channels. Its dimensions make it compatible with large-format cooling layouts and custom loop configurations where a low-profile, wide coldplate is required.

Advantages

The transparent acrylic construction allows visual inspection of coolant and flow paths while contributing minimal thermal resistance when mounted on heat-generating components. The integrated 5V RGB lighting supports synchronized lighting systems and offers aesthetic control without additional external fixtures. The broad contact surface supports efficient heat transfer across wide components, and the overall form factor is suitable for installation in custom water-cooling loops.

Suitable for

• Custom PC water-cooling loops for GPUs or multi-die assemblies
• Enthusiast builds requiring visible coolant flow and lighting integration
• Laboratory or test benches where component temperature visualization is needed

Key specifications

• Material: transparent acrylic top with thermally conductive base interface
• Dimensions: 125 mm (width) × 480 mm (depth) × 42 mm (height)
• Lighting: integrated 5V RGB illumination compatible with common controller standards
• Surface: large flat contact area for broad heat dissipation
• Connection: ports for coolant in/out suitable for standard tubing and fittings

How to use

Mount the coldplate onto the target component following the cooling loop layout, ensuring even contact across the heat source and using an appropriate thermal interface material where required. Connect the coolant inlets and outlets with compatible fittings and verify flow direction matches the loop design. Attach the 5V RGB header to a compatible controller or motherboard RGB connector, and secure the coldplate in place with suitable mounting hardware to maintain consistent pressure and alignment.

Usage recommendations

Inspect seals and fittings after initial installation and during routine maintenance to avoid leaks. Use coolant formulations recommended for PC water cooling and avoid aggressive chemicals that could degrade acrylic. Ensure RGB connections are compatible with 5V control and observe manufacturer's guidance on maximum operating temperatures and flow rates when integrating into an existing cooling system.
