Friends who play with water are aware that both the CPU cold head and the graphics card cold head are made of copper. As the thermal conductivity of aluminum commonly used for heat dissipation is also good, why not use aluminum as a cold head?
In real life, materials with low thermal conductivity are used for insulation materials, such as asbestos and perlite, which are applied because of their slow heat transfer. The electronic chip needs to dissipate heat quickly, which requires the use of a material with a high thermal conductivity, and metal is definitely the first choice. Copper has a thermal conductivity of 377, aluminum is 237, and silver is 412. Silver is too expensive to be used for cold heading, so copper is the best choice.
