The noise level of a laptop fan is often an important indicator as it relates to the user's experience and the performance of the device. Under normal load, the noise of a laptop fan should be between 30 and 45 decibels.

If you think the noise from your laptop fan is out of the normal range, you can try the following to reduce the noise level:

Clean the fan: Clean the heat sink and fan of the laptop regularly.

Control load: Reduce the number of programs and tasks that run simultaneously to reduce the load on the fan.

Heat dissipation pad: The use of heat dissipation pad can provide additional heat dissipation support, reduce temperature, reduce fan speed and noise.
