Power supply
Thermal management

The power supply of an electrical system tends to generate heat. The higher the efficiency, the less heat is generated by the power supply. There are many ways to manage the heat of a power supply unit. The types of cooling generally fall into two categories -- convection and conduction. Common convection methods for cooling electronic power supplies include natural air flow, forced air flow, or other liquid flow over the unit. Common conduction cooling methods include heat sinks, cold plates, and thermal compounds.
