What is essential to apply after installing a new processor?

After installing a new processor, the application of thermal compound is essential for optimal performance and longevity of the processor. Thermal compound improves the thermal interface between the processor and the heat sink or cooling solution. It fills in microscopic imperfections on the surfaces to ensure efficient heat transfer. Without this layer, there may be insufficient heat dissipation, which can lead to overheating and potential damage to the processor.

Using the proper thermal compound is crucial as it allows the heat generated by the processor to be effectively transferred to the cooler, maintaining appropriate operating temperatures. This is particularly important during high-performance tasks where the processor is under heavy load. Neglecting this step could compromise the functionality and lifespan of the new processor. Other options either do not contribute to effective heat management or are inappropriate for use in this context.
