Fans run on Apple computers by default to keep them cool. When the Mac gets too hot, it throttles the CPU, which slows down to mediate the temperature. Some scenarios may cause the fans to work harder to eliminate hot air.
You may be able to hear the fans running on your Mac which is not the most pleasant experience. Or, maybe the fan has stopped running to keep your Mac cool. There are steps you can take to run your fans more or run them less. In any case, if you would like to learn how to manage the fans on your Mac, this tutorial will show you how.
Monitor and Control Your Mac’s Fans
Monitoring and controlling your Mac’s fans encompasses speeding the fans up beyond Apple’s default setting; or slowing it down, perhaps to reduce noise. Whatever approach you take, please note that inappropriate fan settings could lead to damage to your computer. When you make changes to the fan speed, make sure to monitor your computer to make sure the temperature is consistently stable.
