Pacific CLD 480 Radiator The Pacific CLD Series Radiator is a copper radiator built with an highly efficient double-fin design and a brass tank. The radiator is compatible with 120mm high-static pressure fans with 40mm thickness for optimal heat dissipation, the CLD series is manufactured with a "reflow soldering manufacturing process" which provides exceptional cooling performance. High-Density Double Micro-Fin The fin density (FPI: 25) is optimally designed to increase surface area allowing heat to be easily carried away. The performance is significantly improved with increased fan speed, offering superior heat dissipation. High-Quality Copper & Double Fin Radiator Design Optimized Heat Dissipation & Dual-Row Copper Tubes with a Brass Tank Based on our reflow soldering manufacturing process, the Pacific CLD Series is engineered with a thick 40mm radiator along with dual-row 12-set flat tube design and a brass tank. The radiator is optimized for efficiently which allows even heat dissipation from your internal components. Remarkable Expansion Designed for 120mm high-static pressure fans, the Pacific CLD Series allow users to build up aesthetically-superior watercooled PCs as well as incorporate externally-modular upgrades for the systems, delivering the ultimate in custom configurations.
