Metal has good thermal conductivity, but now any notebook has a non-slip rubber pad on the bottom, which cannot be closely attached to the metal heat dissipation base, so the thermal conductivity of metal cannot be fully utilized. Of course, the metal base can better absorb and diffuse the heat emitted from the product. In addition, metals are generally heavier, and due to the high process requirements during manufacturing, once the workmanship is not fine enough, it can easily become a weapon that hurts people.
Aluminum enclosure plastic materials are generally lighter and harder. Many engineering plastics are even stronger than metals. For cost and portability considerations, products with lighter weight and low heat generation can be purchased with a better-designed plastic heat sink base. However, if it is a product with a heavier weight and a higher heat generation, it is recommended to purchase a metal base with a good workmanship.
