The most common heat sink materials are
aluminium alloys.
Aluminium alloy 1050A has one of the higher thermal conductivity values at 229 W/m\u2022K but is mechanically soft.
Aluminium alloys 6060 and 6063 are commonly used, with thermal conductivity values of 166 and 201 W/m\u2022K, respectively.

The components that generate the most heat in your computer are the CPU (central processing unit), video card (if your computer has one), and the power supply. They always have some cooling, usually a fan. Other components that may have a heat sink include the north bridge, south bridge, and memory.Nov 13, 2018

The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power. In most cases, heat sinks are used in conjunction with fans.
