## Long description

The Thermaltake CL420 Radiator block is a 420mm liquid-cooling radiator built from high-quality copper with a sleek black finish. Measuring 147.8 mm width, 467.5 mm depth and 64 mm height, this radiator block uses a triple-row copper tube layout, high-density copper fins and brass tank construction to provide effective heat transfer for demanding PC cooling configurations. Integrated G1/4" threads and rigid connections simplify installation and improve leak resistance, while stainless steel side panels increase structural durability without adding unnecessary weight. The CL420 is designed to work with high-static pressure 120/140 mm fans and is suitable for custom water-cooling loops in enthusiast and high-performance builds.
Advantages
The copper construction and triple-row tube design ensure efficient heat dissipation across a wide range of airflow conditions, while the high-density fin pattern (FPI 14) improves performance as fan speed increases. The brass tank and reflow-soldered joints provide consistent thermal transfer and long-term reliability. Stainless steel side panels enhance mechanical strength and reduce deformation risk during installation. Integrated G1/4" threads and rigid fittings help create a secure, leak-resistant connection to the rest of the loop.
Suitable for
Custom liquid-cooling loops for high-performance CPUs and multi-GPU systems
Enthusiast builds requiring a 420 mm radiator mount
Systems using 120 mm or 140 mm high-static pressure fans
Those seeking a durable radiator with stainless steel side panels and copper core

How to use
Mount the radiator in your case using the appropriate 140 mm or 120 mm fan holes for a 420 mm configuration. Attach high-static pressure fans to the radiator surfaces, orienting airflow for optimal heat removal from the loop. Connect the radiator to the rest of your liquid-cooling loop using G1/4" threaded fittings and ensure all joints are tightened to the manufacturer's torque recommendations. Fill and bleed the system according to your cooling loop components' instructions, then run a leak test before powering other components. Ensure sufficient airflow in the case and verify fan curves to balance noise and cooling performance.
Usage recommendations
For best results, pair the CL420 radiator with high-static pressure 140 mm fans and position the radiator where it can receive unobstructed airflow. Use approved cooling fluids and compatible G1/4" fittings; perform a thorough leak test after assembly and during initial operation. Regularly inspect the radiator fins and side panels for dust build-up and clean as needed to maintain optimal thermal performance.
