Water block Barrow LTYK3-04I Black Acrylic RGB for CPU cooling, acrylic top, RGB lighting

Barrow LTYK3-04I Black is an acrylic-top water block designed for CPU liquid-cooling loops. The water block provides a flat contact surface for effective heat transfer from the processor to the coolant and features integrated RGB lighting beneath a black acrylic top. It connects to custom cooling loops using standard fittings and is intended for installation in custom PC builds where both thermal performance and visual integration are required.

Advantages

The unit combines an acrylic top with an internal illuminated area to deliver a clear visual effect while maintaining compatibility with common liquid-cooling fittings. Its construction allows direct coolant flow over the cold plate area, supporting efficient heat removal from modern CPUs. The compact footprint simplifies installation in a variety of case layouts and enables integration into multi-component loops without significant spatial compromises.

Suitable for

• Custom PC liquid-cooling loops for desktop processors
• System builders who want integrated RGB illumination in the cooling loop
• Upgrading or replacing an existing CPU water block for improved aesthetics
• Enthusiast systems combining multiple water-cooled components

Key specifications

• Top material: black acrylic with integrated RGB lighting
• Cold plate contact: designed for direct CPU heat transfer
• Cooling loop connection: compatible with standard liquid-cooling fittings
• Compatibility: intended for desktop CPU socket types (verify mechanical fit before installation)
• Primary function: coolant flow-through water block for CPU thermal management

How to use

Install the water block on the processor following the motherboard and case manufacturer's instructions, ensuring the cold plate aligns with the CPU heatspreader. Use appropriate thermal interface material between the CPU and the cold plate and secure the block with the supplied mounting hardware or a compatible bracket. Connect inlet and outlet ports to the rest of the loop using suitable fittings and tubing rated for liquid-cooling systems. Verify that RGB connectors are mated to the system controller or RGB header if lighting control is required. Perform a leak test and circulate coolant before powering on the system components.

Recommendations

Use corrosion- and biocide-resistant coolant and compatible fittings to prolong component life. Check clearance and mounting compatibility with your specific CPU socket and motherboard layout. Follow standard leak-test procedures and monitor coolant condition over time to maintain optimal thermal performance.
