Fault phenomenon: A laptop computer found that the CPU fan still did not turn when the computer was running to a high temperature on the back panel. After inspection, it was found that the computer would turn once when starting self inspection, indicating that the fan had no problem in braking. But the back panel still doesn't turn when the temperature is very high.
Handling method: CPU fan is mainly used for heat dissipation of CPU. Only when the CPU temperature is higher than about 70 ℃ can it be rotated for heat dissipation. In addition, the high temperature of the back panel is not necessarily caused by the CPU. The heat of hard disk, memory, video card, motherboard and other accessories may gather here. Therefore, the high temperature of the back panel is inevitably related to whether the CPU fan is rotating. In addition, it is recommended to run a large game for testing at the same time. If the CPU fan does not turn after a period of time, it may be a problem with the CPU fan.
