## Long description

THERMALTAKE CL-W040-CU00BL-A is a copper CPU cooler accessory with a black finish, designed for integration into PC cooling assemblies and custom cooling projects. With a height of 26 mm and a weight of 14 g, this compact metal component provides thermal conductivity typical of copper parts used in CPU cooling setups and water-cooling fittings. The product is intended as a mechanical and thermal interface element within cooling loops and mounting assemblies where a short, durable copper fitting is required.
Advantages
The copper construction ensures effective heat transfer and structural stability while the black surface treatment provides corrosion resistance and a consistent visual appearance in black-themed builds. Its compact dimensions and light weight make it suitable for tight installation spaces and for use in modular liquid-cooling assemblies. The simple design and metal material offer long-term durability compared with non-metal alternatives.
Suitable for (tasks / use cases)
 Integration into CPU cooling assemblies and custom air- or liquid-cooling projects
 Use as a short copper fitting or adapter in compact cooling loops
 Replacement or upgrade part for Thermaltake Pacific series and similar water-cooling components
 Applications requiring a corrosion-resistant black-finished copper connector in tight spaces
Key specifications
 Material: Copper
 Finish: Black plated/treated surface
 Height: 26 mm
 Weight: 14 g
 Designed for: PC CPU cooling and custom water-cooling assemblies
How to use
Install the copper accessory as part of your cooling assembly according to the cooling loop or mounting instructions for your system. Ensure compatible mating threads or fittings and use the appropriate tubing or connectors for a secure, leak-resistant connection. Tighten connections to the torque recommended by your component manufacturers and verify alignment to avoid strain on adjacent parts. If used in liquid-cooling loops, check O-rings and seals on adjoining fittings and replace or lubricate them as required.
Usage recommendations
Before finalizing installation, perform a pressure or leak test on the loop according to standard liquid-cooling procedures and inspect the black finish for any surface contamination. Use compatible tubing inner diameter and G1/4"-threaded adapters where required; avoid over-tightening to prevent thread or sealing damage. Regularly inspect connections during maintenance intervals to ensure continued performance and corrosion resistance.
