My macbook pro m2 often heats up suddenly when using safari and plugging in the charger

Hello NguyenDuong183,

We understand that you're experiencing unexpected warmth from your MacBook. There is a great article that can help you manage the operating temperatures for your device.

Keep your Mac notebook within acceptable operating temperatures - Apple Support

Tips to manage the operating temperature:

- Make sure that you’ve installed all Mac software updates.

- Use your Mac notebook where the ambient temperature is between 50° and 95° F (10° and 35° C). - - Don’t leave your Mac notebook in your car, because temperatures in parked cars can exceed this range. You should also use your Mac notebook where the relative humidity is between 0% and 95% (noncondensing).

- Use your Mac notebook on a stable work surface that allows for good ventilation. Don’t use your Mac notebook in your bed, on a pillow, or under bedding.

- Don’t put anything over the keyboard. 

- If your Mac notebook has ventilation openings, don't put anything into them. 

- Use only Apple-authorized power adapters.

If what you're experiencing seems to be outside of the details noted in the posted article, it may be a good idea to contact Apple Support for help. You can reach them at Get Support.

Best regards.
