1. Understanding CPU Core Temperature

The CPU (Central Processing Unit) is the brain of your computer, responsible for executing instructions and performing calculations. It consists of multiple cores, each capable of handling individual tasks. The temperature of the CPU core refers to the temperature of these individual processing units.

The CPU generates heat as it operates, and this heat needs to be dissipated to prevent overheating. The CPU core temperature is a measure of how hot the cores get during operation. By monitoring this temperature, users can ensure that their CPU is within safe operating limits.

Temperature is typically measured in degrees Celsius (°C). Each CPU has a maximum temperature specified by the manufacturer, beyond which it can be considered unsafe to operate. Exceeding this maximum temperature, such as 100°C, can result in thermal throttling, reduced performance, and potential damage to the CPU.

2. What Happens at 100°C

When the CPU core temperature reaches 100°C, it enters a critical state. At this temperature, the CPU may start experiencing thermal throttling, which is a mechanism designed to protect the CPU from overheating. Thermal throttling reduces the CPU's clock speed, i.e., the speed at which it can execute instructions, to minimize heat generation and aid in cooling.

If thermal throttling occurs, it can lead to a significant decrease in performance. Tasks that used to be executed quickly may take longer to complete, affecting overall system responsiveness. Applications that require high CPU usage, such as gaming or video editing software, may not perform as expected when the CPU is consistently operating at 100°C.

In addition to thermal throttling, prolonged exposure to high temperatures can damage the CPU over time. The continuous operation at 100°C can degrade the CPU's lifespan and potentially cause permanent damage to its delicate components.
