Heat Transfer — CompTIA A+ Core 1 (220-1101) Practice Questions

Heat transfer is the physical process by which thermal energy moves from a hot component to a cooler medium, and it underlies all cooling strategies tested on the 220-1101. Conduction moves heat through direct contact between a CPU die and a heatsink, convection carries it away via airflow, and radiation plays a minor role in passive designs. Thermal interface material, such as thermal paste, maximizes conductive contact between the processor and heatsink base. Understanding heat transfer helps technicians troubleshoot overheating issues and apply appropriate cooling solutions.
