Product information

Description

THERMALTAKE CL-W237-CU00BL-A is a copper liquid-cooling radiator block finished in black, sized 119 × 406 × 40 mm and weighing 1.002 kg. Designed as a component for custom PC liquid cooling loops, this radiator block improves heat dissipation for CPUs and other heat-generating components. The product is intended for integration into water-cooling systems where a compact, high-conductivity copper radiator is required.

Advantages

The copper construction provides high thermal conductivity for efficient heat transfer from coolant to fins. The black finish offers a neutral appearance that integrates into a variety of system builds. Its compact 119 × 406 × 40 mm form factor and 1.002 kg weight make it suitable for installations where space is limited but copper performance is desired. The product is made for liquid-cooling loops and supports common liquid-cooling installation approaches.

Suitable for

  • Custom PC liquid cooling loops for CPU cooling
  • Cooling other heat-generating components in compact desktop builds
  • Systems requiring a copper radiator with a black finish

Key specifications

  • Material: Copper (radiator core)
  • Finish: Black
  • Dimensions (W × L × H): 119 × 406 × 40 mm
  • Weight: 1.002 kg

How to use

Install the radiator block into a compatible liquid-cooling loop following the cooling system and case manufacturer instructions. Mount the radiator securely in the chosen location, connect inlet and outlet fittings using appropriate G1/4" or compatible threaded fittings and tubing, and ensure all connections are tightened to prevent leaks. Fill the loop with the recommended coolant, purge air from the system, and verify proper flow and temperature before regular operation. Observe standard safety practices for liquid-cooling maintenance.

Usage recommendations

Use corrosion-resistant fittings and coolant formulated for mixed-metal loops if other metals are present in the system. Periodically inspect fittings and tubing for signs of wear or leakage, and perform routine coolant changes according to coolant manufacturer guidance to maintain thermal performance.

Reasons to buy

Dual-row copper tubes with brass tank for superior heat transfer

The THERMALTAKE Pacific CLM Series radiator block features a robust dual-row, 12-set flat copper tube layout combined with a brass tank and a thick 40 mm core to maximize thermal capacity. This flow-through design routes coolant down one side, across the bottom chamber, and back up the opposite side to increase contact time and improve heat evacuation for more efficient cooling in custom liquid loops.

High-density copper fin array tuned for fan performance

Engineered with an optimal fin-per-inch (FPI: 14) copper fin density, the radiator delivers improved thermal exchange as fan speed increases. It is especially effective when paired with high-air-volume or high-static-pressure 120 mm fans, producing stronger cooling performance under heavier loads.

Durable stainless-steel side panels with reduced weight

Unlike many pure-copper radiators, this model uses stainless-steel side panels to enhance structural strength and durability while keeping overall weight low. The combination preserves long-term reliability without compromising the radiator’s thermal design.

Premium reflow soldering for reliable thermal joints

The radiator is manufactured using a high-temperature reflow soldering process (482°F / 250°C) in a controlled atmosphere, producing clean, impurity-free joints. This method ensures the materials fuse effectively from tubes to fins, yielding consistent thermal transfer and durable connections across the entire assembly.

Designed for custom builds and 120 mm high-static-pressure fans

With compact dimensions of 119 × 406 × 40 mm and a black finish, the CL-W237-CU00BL-A radiator (weight 1.002 kg) is ideal for aesthetically-focused, externally modular watercooled PC builds. It supports 120 mm high-static-pressure fans to enable flexible, high-performance custom configurations.
