How to Tell if My Mac is Overheating?
The most obvious way to tell if your Mac is overheating is by observing the temperature of the Mac. If it is too hot to place on the bed or lap, then it is overheating. If it is blowing out hot air from the airways, it is overheating.
Another potent and sure way to tell if your Mac is overheating is if the fan starts rolling. The function of the fan in your Mac is to cool it down whenever things start to get hot inside. Therefore, the fan will only start rolling when it is triggered by too much heat in the system. This means that when you hear the fan rolling, or making a mild noise, your Mac is overheating.
