Excessive heat can damage electronic devices. In order to combat the problem of heat generated in electric circuits heatsinks are sometimes attached to components that generate the most heat. Heatsinks are made of thermally conductive materials and have folds made into them in order to increase surface area so that the heat from the component is dissipated into the air quicker. Heatsinks are also sometimes attached with a layer of thermally conductive past. The paste helps to insure that heat is conducted efficiently between the component and the heatsink.
