Product information

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

Key specifications

  • Material: Copper radiator core with brass tank and stainless steel side panels
  • Radiator size: 420 mm (fits triple 140 mm fan configuration)
  • Dimensions: 147.8 mm (W) x 467.5 mm (D) x 64 mm (H)
  • Fin density: High-density fins (FPI 14)
  • Tube design: Triple-row flat tube array for improved flow and heat transfer
  • Mounting: Compatible with 120 mm and 140 mm high-static pressure fans
  • Connections: Integrated G1/4" threaded ports for fittings
  • Weight: 2.035 kg
  • Colour: Black

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.

Reasons to buy

High-Performance 420mm Copper Radiator for Liquid Cooling

The Thermaltake Pacific CL420 Radiator (model CL-W193-CU00BL-A) is a 420mm copper radiator engineered for demanding liquid-cooled PCs. Its 64mm thickness, copper construction and sleek black finish deliver efficient heat dissipation and a premium look for high-performance builds. Designed to integrate seamlessly into CPU cooling systems, it supports robust thermal performance while remaining compatible with a wide range of cooling setups.

Triple-Row Copper Tubes and Brass Tank for Superior Heat Transfer

Engineered with a triple-row, 16-set flat tube design and a brass tank, the CL420 promotes effective coolant routing—flowing down one side, across the bottom chamber, and back up the other side—to maximize thermal capacity and improve overall heat transfer under load.

High-Density Copper Fin Array Optimized for Fans

The radiator features a high fin density (14 FPI) that’s optimized for high air volume and high-static pressure fans. Cooling performance scales effectively with fan speed, delivering superior thermal efficiency during intense operation.

Durable Stainless Steel Side Panels with Reduced Weight

Unlike typical copper radiators, the Pacific CL420 uses stainless steel side panels that enhance structural strength and durability while reducing overall weight—providing a sturdy, long-lasting foundation for custom water-cooling loops.

Premium Reflow Soldering Manufacturing for Reliability

The CL420 is manufactured using a controlled atmosphere reflow soldering process at 250°C (482°F), ensuring clean joints, strong connections and optimal thermal contact between tubes and fins for reliable long-term performance.

Designed for Flexible, High-Performance Builds

Compatible with 140mm high-static pressure fans (and suitable for 120mm/140mm fan configurations), this radiator supports versatile, aesthetically refined watercooling layouts. At 467.5 mm depth, 147.8 mm width and 64 mm height and weighing 2.035 kg, it fits custom configurations while providing the cooling capacity required for demanding systems.
