Why is the MacBook Airs overheating

Maintain acceptable operating temperatures for your Mac notebook

Mac notebooks comply with all temperature limits that are specified in national and international safety standards. Follow the instructions in the user manual for safety and handling.

Mac notebooks are equipped with sensors that detect changes in temperature within the computer. If your Mac notebook has fans, these are automatically activated to cool critical components.

Here are some tips for managing the operating temperature:

  • Make sure you have all Mac software updates and all the latest firmware updates installed.
  • Use your Mac notebook in places with an ambient temperature between 10 ° and 35 ° C. Do not leave your Mac notebook in the car, as the temperature in parked cars can exceed the permissible temperature range. You should also use your Mac notebook in locations with a relative humidity between 0% and 95% (non-condensing).
  • Use your Mac notebook on a stable work surface that allows good ventilation. Don't use your Mac notebook in your bed, on a pillow, or under blankets.
  • Don't put anything over the keyboard.
  • If your Mac notebook has vents, keep them clear at all times.
  • Use only Apple-approved power adapters. Take measures to prevent the power supply from overheating.

If your Mac notebook gets warm even during tasks that don't require intensive calculations or if fans run for a long time, check the CPU activity with the activity meter. Look for processes that are malfunctioning that can place significant CPU load on the CPU and see if Spotlight is indexing your hard drive. You may also need to reset the System Management Controller (SMC) on the MacBook.

If you use third-party apps that measure the temperature of your notebook computer, be aware that they do not measure the temperature of the external case. The case temperature is significantly lower. Never use third-party apps to diagnose possible hardware problems.

Contact Apple if you have any problems with the operating temperature of your Mac notebook. Alternatively, you can visit an Apple Store or Apple Authorized Service Provider.
