How loud is the laptop?

when the fan is started under high load or the CPU temperature is high, it will hear obvious wind, which should be very quiet and almost negligible during normal operation. If it is noisy, first check whether the air outlet is blocked by dust. If it is still noisy, open the back cover to check whether there is too much dust in the fan, and properly add some lubricating oil to the fan. If it is still noisy, please check whether the silicone grease on the CPU has been worn out, and the CPU is not radiating enough, so that the fan runs for a long time.
