It is normal for the laptop's fan to produce a certain sound when it is working because of the rotation of the fan and the flow of air.
The rotation of the fan is related to the temperature of the CPU, such as the use of high ambient temperature, too many running programs or large software will cause the CPU temperature to rise, when the CPU temperature increases, the fan will rotate more frequently, and the sound will be louder.
If the sound is particularly loud, or you feel that it is abnormal, it is recommended that you go to the nearest official service center and have an engineer test it on site.
