What is a common cause of computer overheating?

A common cause of computer overheating is dust buildup blocking ventilation. When dust collects in the vents, fans, and heatsinks, it obstructs airflow, which is essential for dissipating heat generated by the computer's components, such as the CPU and GPU. This blockage can lead to higher internal temperatures, as the cooling system becomes less effective.

Proper airflow is crucial for maintaining optimal operating temperatures; when it is restricted, components may heat up beyond their safe operating levels. Over time, excessive heat can cause system instability, performance issues, or even permanent damage to the hardware. Regular cleaning and maintenance of the computer’s interior and cooling systems can help prevent overheating caused by dust accumulation.
