Thermaltake Pacific CL480 Cooling Radiator

The Thermaltake Pacific CL480 Cooling Radiator is engineered for enthusiasts who demand uncompromising thermal performance and dependable, long-term reliability in a flagship water-cooling solution. This 480mm copper radiator features a high-density copper fin design paired with a sturdy brass tank, delivering exceptional heat transfer and durability that stand up to intense overclocking, multi-component cooling, and compact, high-performance builds. Built to work seamlessly with 120mm high-static pressure fans, the CL480 optimizes airflow through dense fin packs, ensuring consistent cooling even when airflow is constrained by case geometry or cable management. Crafted from premium materials, it offers reliable operation under heavy loads, minimal thermal throttling, and an aesthetic that complements modern PC builds with a clean, industrial look. Whether you are assembling a gaming rig, a workstation, or a multi-rocket cooling loop, the Pacific CL480 stands out as a backbone component that helps you push limits while preserving acoustic comfort and system stability.

• High-density copper fin design — The CL480’s core uses a dense copper fin array to maximize contact area with coolant, promoting rapid heat transfer from CPU, GPU, and VRMs to the flowing liquid. This efficient micro-fin structure reduces thermal resistance, enabling lower coolant temperatures under load and enabling sustained performance in long gaming sessions or workstation tasks.
• Brass tank construction — A robust brass end tank provides exceptional strength and resilience against corrosion and pressure variations common in custom loops. The brass reservoir helps maintain structural integrity during thermo-fluid cycling, ensuring leak resistance and long-term reliability even after repeated fill-bleed cycles and routine maintenance.
• Designed for 120mm high-static pressure fans — The radiator is optimized for 120mm fans that generate higher static pressure, ensuring airflow penetrates the dense fin stack efficiently. This pairing yields superior cooling efficiency in restrictive or tightly packed chassis environments where airflow is a premium and noise containment matters.
• Premium materials, premium performance — The combination of copper fins and brass tank reflects Thermaltake’s commitment to quality and durability. These materials deliver excellent thermal conductivity, robust durability, and a premium look that integrates well with high-end build aesthetics while delivering consistent cooling performance under demanding workloads.
• Versatile cooling solution for multi-component loops — The 480mm radiator size provides ample surface area for CPU, GPUs, and other hot components in a single loop or in multi-radiator configurations. Its balanced weight and mounting options help fit a wide range of chassis designs, making it a flexible choice for custom water-cooling enthusiasts aiming for high performance with clean cable routing and tidy aesthetics.

how to install Thermaltake Pacific CL480 Cooling Radiator

Installing the Pacific CL480 is a straightforward process for builders familiar with custom water-cooling, but it benefits from careful planning to maximize performance and reliability. Start by selecting a suitable mounting location in your case, typically the front or top radiator bays that can accommodate a 480mm unit. Confirm clearance for the radiator length, fan mounting hardware, tubing routing, and any clearance needed for reservoirs or pump tops. Once you have a clear plan, assemble the fans to the radiator with the desired orientation. A push-pull configuration can yield additional airflow through the dense fin stack, but a standard push setup is perfectly adequate for many builds. Secure the radiator in its mounting location using the appropriate screws, ensuring a firm, level fit that does not distort the frame. Route and measure tubing to avoid sharp bends; use compatible fittings that seal securely to prevent leaks and minimize the risk of kinks or excessive stress on the tubing. Connect the radiator to your pump and reservoir, ensuring the flow path is logical (inlet from reservoir to pump, then through the radiator, and onward to the CPU/GPU blocks). Fill the loop with a suitable coolant, purge air from the system, and perform a leak test before powering on the computer. Once installed, verify that all fans run smoothly, monitor coolant temperatures, and fine-tune fan curves to balance cooling performance with acoustics. Regular maintenance, including periodic checks for any signs of leakage, dust accumulation on the fins, and coolant quality, will help preserve peak performance over time.

Frequently asked questions

• What makes the Thermaltake Pacific CL480 different from other radiators? The CL480 combines a 480mm copper radiator core with a brass tank and a design optimized for 120mm high-static pressure fans, delivering high cooling capacity and durability in a larger format that suits demanding multi-component setups and overclocked systems.
• Is this radiator suitable for compact cases? The CL480 is best in cases with adequate space for a 480mm radiator. If your case cannot accommodate full-length radiators, consider alternative sizes or configurations that maintain proper airflow and clearance while preserving cooling efficiency.
• Do I need to use 120mm high-static pressure fans with the CL480? Yes, the radiator is optimized for these fans to maximize airflow through the dense fin structure, ensuring consistent cooling even under heavy loads. Using the recommended fan type helps you achieve the best performance-to-noise balance.
• What maintenance does the CL480 require? Regular maintenance includes inspecting for dust buildup on the fins, ensuring fittings and tubing remain leak-free, and replacing coolant as part of routine loop servicing. Periodic cleaning helps preserve heat transfer efficiency and prolongs component life.
• Can this radiator be used in custom loops with multiple components? Absolutely. The 480mm size provides ample surface area for CPU and GPU cooling, VRMs, and other hot components in a single loop or in multi-r radiator configurations, depending on your chassis layout and pump capacity.
