Heat sink compound is used to fill gaps between the cpu (central processing unit) or other heat generating components and the mechanical heat sink. The heat sink is attached to the microprocessor to regulate its temperature and prevent it from overheating. How To Make Good Thermal Paste At Home With Common Items - Youtube They do this by increasing the device’s surface area. How does heat sink compound work . By applying thermal paste between a hot component and its heat sink, the paste will fill in any air. The mechanical heat sink, a passive component made of a conductive metal, is placed over the cpu. The thermal paste is placed between the heat sink and the cpu, or gpu and it fills all gaps. What does thermal paste do? A heat sink is a mechanical component that is attached to an electrical component for the sake of transferring heat from the electrical component into the surrounding environment. Thus it produces better conductivity of heat. If the fluid medium...
