Which component is often replaced to resolve overheating issues in HP desktops?

Overheating issues in HP desktops are frequently attributed to inadequate heat dissipation, which is primarily handled by the cooling fan and heat sink. The cooling fan is responsible for circulating air around essential components, while the heat sink absorbs and disperses heat from the processor and other critical parts. When either the cooling fan or heat sink fails or becomes obstructed by dust and debris, it can result in insufficient cooling, causing the system to overheat.

Replacing the cooling fan or heat sink effectively addresses these overheating issues by restoring the system's ability to maintain optimal operating temperatures. This ensures that the components function correctly and prevents thermal throttling or damage that can arise from excessive heat.
