Descripción

Specify 6 types of thickness (0.3/0.5/0.8/1.0/1.2/1.5 mm) to choose from. The thermal conductivity is up to 401w/mk, almost 409w/mk silver, much higher than ordinary copper cushions (20-30w/mk). Exposure to air, the copper surface inevitably oxidises and becomes dark, but the cooling effect is not affected. If you still worry, you can polish the surface of this copper disc with fine sandpaper or toothpaste. Can solve frequent laptop crash and other problems caused by thermal conductivity. Can be applied to the north and south bridge connection of the desktop computer, graphics card heat conduction.
