Radiator block THERMALTAKE CL360 — copper, 405×132×64 mm, 1/4 inch thread, 1.66 kg, black

THERMALTAKE CL360 radiator block is a copper liquid-cooling radiator designed for custom PC cooling loops. With external dimensions of 405 × 132 × 64 mm and a matte black finish, this radiator serves as a compact heat exchanger for water-cooling systems. The unit weighs approximately 1.66 kg and uses standard 1/4" connecting threads for inlet and outlet fittings, offering compatibility with commonly available tubing and fittings in custom builds.

Advantages

The copper construction provides effective thermal conductivity to transfer heat from the coolant to ambient air. The 1/4" threaded ports simplify installation with standard fittings and adapters. Its 405 × 132 × 64 mm footprint fits many mid- and full-tower enclosures or external radiator mounts, while the black finish integrates with a wide range of system aesthetics. The radiator is intended specifically for liquid cooling loops and is built to be used with water-based coolants.

Suitable for

• Custom CPU water-cooling loops in desktop PCs
• GPU or chipset cooling when integrated into a single-loop system
• Compact or standard tower cases with support for 360 mm radiator length
• External radiator mounting in custom cooling testbeds or open rigs

Key specifications

• Material: Copper
• External dimensions (L × W × H): 405 × 132 × 64 mm
• Weight: 1.66 kg
• Connecting thread: 1/4" (standard fittings)
• Finish: Black
• Designed for: Liquid (water-based) cooling

How to use

Install the radiator into your case or external mount where a 360 mm radiator fits, aligning mounting holes with fan or bracket points. Fit 1/4" threaded fittings to the inlet and outlet ports and connect tubing suitable for liquid cooling. Ensure the loop includes a properly sized pump, reservoir, and compatible coolant. After assembly, perform leak testing and a controlled fill and run cycle before normal operation to confirm sealing and flow.

Recommendations

Use corrosion-inhibiting, manufacturer-recommended coolants in single- or multi-component loops and perform regular maintenance such as coolant replacement and visual inspection. Mount fans to the radiator to achieve the desired airflow and thermal performance; select fan speed and static-pressure fans appropriate for radiator fin density. Avoid over-tightening fittings to prevent thread or port damage.
