CPU Cooler Accessory THERMALTAKE CL-W053-CU00BL-A copper part, black, 42×28.3×22 mm

Thermaltake CL-W053-CU00BL-A is a compact copper cooling-system part designed for integration into CPU cooling assemblies. Finished in black, the solid copper component measures 42 × 28.3 × 22 mm and weighs 0.093 kg. It serves as a replacement or upgrade element for heatsinks, water blocks and custom cooling loops where direct copper thermal conduction and a small form factor are required.

Advantages

The copper construction ensures good thermal conductivity for improved heat transfer when used as part of a cooling path. Its black finish provides visual compatibility with modern PC builds and cooling hardware. The small footprint and modest weight make it suitable for constrained spaces and for retrofitting into existing assemblies without significant mechanical load.

Suitable for

• Integration with CPU heatsinks and contact plates
• Use inside custom water blocks or cold plates
• Replacement part in small-form cooling assemblies
• Custom cooling loop upgrades requiring copper conduction elements

Key specifications

• Material: Copper
• Finish: Black
• Dimensions: 42 × 28.3 × 22 mm
• Weight: 0.093 kg

How to use

Install the copper part in accordance with the cooling system design: position it to ensure solid contact with the mating surface of the heatsink, water block or cold plate, and secure it using the original mounting points or compatible fasteners. Ensure mating surfaces are clean and, where appropriate, use thermal interface material to maximize thermal transfer. Check for alignment and clearance with nearby components before final fastening.

Usage recommendations

Handle the part carefully to avoid deforming contact surfaces. When used in liquid cooling assemblies, confirm compatibility with sealing and mounting arrangements; inspect seals and fittings after installation and during initial operation to rule out leaks. For optimal heat transfer, clean surfaces and apply appropriate thermal interface material between the copper piece and the component it contacts.
