What are the consequences of high CPU temperature

    The temperature of the CPU has a crucial impact on overall performance and stability. The CPU is composed of silicon wafers, and when the temperature rises, the performance of the transistor will be damaged, leading to a decrease in the efficiency of the transistor and a decrease in overall CPU performance. Of course, excessively high temperatures may also cause permanent damage to the CPU.

    Although most CPUs now have temperature walls and motherboard power walls for protection, prolonged high temperatures are clearly prone to damage. Because the CPU is not solely composed of silicon, it also has other components such as a PCB board, core, and top cover. These components may have different coefficients of expansion when heated due to their different materials. This means that under extreme temperature conditions, due to the varying degrees of thermal expansion and contraction of different components, gaps may appear between components, resulting in virtual welding or fracture.

    So to ensure the safe operation of the CPU, the manufacturer will integrate a temperature monitoring module internally. This module can detect the working temperature of the CPU in real-time. Once the temperature is detected to be too high, the CPU will automatically reduce the operating frequency in order to lower the temperature and protect the hardware. In extreme cases, to avoid damage, the CPU may even automatically shut down.
So if your computer frequently experiences blue screens or sudden drops in performance, it is likely due to high CPU temperature. At this point, tools such as AIDA64 can be used to monitor the real-time temperature of the CPU. If abnormal temperature is found, the radiator should be checked and replaced in a timely manner.

    As for the suitable working temperature of the CPU, generally speaking, the standby temperature of desktop CPUs should be controlled within 40 ℃, and should not exceed 90 ℃ when fully loaded. For laptops, due to their design limitations on heat dissipation, the temperature is relatively high, but ideally it should not exceed 100 ℃. Therefore, ensuring good CPU cooling not only improves performance, but also protects data and hardware security.
