Why does my macbook air get hot after watching the video? The exhaust fan keeps turning. The temperature of cpu is also very high.

This is normal. My fans sometimes complain for no reason, and sometimes even complain about everything.

But usually not. If you just watch videos occasionally, it may be hot weather. In fact, macbook is not good at heat dissipation, especially in summer, the hottest month, when you turn on the computer, and then the location of the computer is placed. If you put it on your body or quilt, the computer is particularly prone to heat. Because of its poor heat dissipation, it will be better to put it on an ordinary desk, and the cooling rack will be more effective. The third reason is that the vent is blocked, and sticking a keyboard film on the keyboard will also hinder heat dissipation.

Generally speaking, summer is inevitable, so is everyone.
