Water cooler Barrow LTYK3A-04 V2 White RGB Acrylic — CPU liquid cooling block, acrylic top, RGB lighting

Barrow LTYK3A-04 V2 White RGB Acrylic is a CPU liquid cooling block with a clear acrylic top and integrated RGB lighting. Intended for custom water-cooling loops, it provides direct-contact cooling of the processor heat spreader and supports standard water-cooling fittings. The white finish is suited to light-colour cases and builds, while the RGB illumination allows visual coordination with other components. This block is designed to help lower CPU temperatures and maintain system stability during sustained loads.

Advantages

The acrylic top offers good visibility of coolant flow and RGB effects while the cold plate and internal microchannel design enable effective heat transfer from the CPU. Compatibility with standard fittings makes installation straightforward in most custom loops. The white housing helps integrate the block into bright-themed systems, and the built-in RGB lighting can be synced with compatible controllers for coherent system aesthetics.

Suitable for

• Custom desktop water-cooling loops for gaming and workstation PCs
• Systems where visual aesthetics and RGB lighting are important
• Processors requiring enhanced cooling under sustained high loads

Key specifications

• Material: acrylic top with metal cold plate
• Cooling type: direct-contact CPU water block for liquid cooling loops
• Lighting: integrated RGB illumination compatible with common RGB controllers
• Finish: white housing for light-themed builds
• Fittings: compatible with standard water-cooling fittings and tubing sizes

How to use

Mount the block directly onto the CPU following the motherboard and block manufacturer torque recommendations for mounting hardware. Ensure the cold plate has clean contact with the CPU heat spreader and use a thin, even layer of thermal compound. Connect inlet and outlet tubing using compatible fittings, verify flow direction within the loop, and integrate the RGB connector with your controller or motherboard header as required. After installation, perform a pressure and leak test on the loop before powering the rest of the system.

Usage recommendations

During setup and maintenance, use compatible coolant and avoid aggressive additives that can damage acrylic surfaces. Periodically inspect fittings and tubing for signs of wear or leakage, and clean the block and loop components according to water-cooling best practices to maintain thermal performance and lighting clarity.
