What happens if you don't clean the heat sink before installing a new processor?

Cleaning the heat sink before installing a new processor is critical for ensuring effective thermal conductivity. The primary function of the heat sink is to dissipate heat generated by the processor, preventing it from overheating during operation. If the heat sink is not cleaned, any residual thermal paste or debris can prevent proper contact between the heat sink and the processor. This can create air gaps, which significantly reduce the heat transfer efficiency.

When the heat sink fails to adequately dissipate the heat, the processor's temperature can rise above safe operating levels, leading to overheating. Overheating can result in thermal throttling, where the processor slows down to prevent damage, and in severe cases, it can cause permanent damage to the processor. Therefore, ensuring that the heat sink is clean and properly seated during installation is essential for maintaining optimal processor performance and longevity.
