Final answer:
Thermal paste is applied between the CPU and CPU cooler to improve heat transfer. It fills in gaps and helps dissipate the heat generated by the CPU.
Step-by-step explanation:
When installing a CPU cooler, a thermal paste or thermal compound is typically applied between the CPU and the cooler. The purpose of the thermal paste is to fill in any microscopic gaps between the two surfaces, allowing for better heat transfer. It helps to dissipate the heat generated by the CPU to the cooler more efficiently.
The thermal paste is applied in a thin layer onto the surface of the CPU. It should be evenly spread to ensure full contact between the CPU and cooler. Excess paste can hinder heat transfer, so it's important not to apply too much.
By using thermal paste, you can avoid air pockets or gaps that would otherwise insulate the CPU, leading to overheating.
