Intended Tubing Size
The CHC-25-L06 is a liquid cooler for Radeon 1800XL/XT, 1900XT/XTX, and 1950XT/XTX voltage regulator circuits. It
replaces the rear "VREG" heat sink of these video cards when liquid cooling the main GPU (which removes the default
air flow). This product is not compatible with the Radeon X1950Pro.
The CHC-25-L06 is an anodized aluminum block with rotational nickel-plated brass
compression fittings. The cooler mounts via two threaded pegs that use the original heat sink mounting holes.
Liquid Coolants
Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use silver with nickel in the same system.
