When a CPU overheats, it can lead to decreased performance and stability issues. The high temperature can cause the CPU to throttle its frequency, which slows down the processing speed to prevent further damage.
In severe cases, the heat can cause permanent damage to the CPU, leading to hardware failure. Overheating can be caused by several factors such as clogged air vents, insufficient cooling solutions, high ambient temperature, and high CPU utilization.
It's important to monitor the temperature of a CPU and ensure adequate cooling to prevent overheating.
