Worse than that, the M1 MacBook Air doesn't even have a fan, making it potentially more prone to overheating if you manage to push the Apple Silicon chip hard enough. It's likely that this problem is down to the compact design with only a single vent-at the hinge of the screen-to aid heat dispersal. The MacBook Air from 2020 appears to be particularly prone to overheating problems. These are issues that every computer contends with, but MacBook Air models seem to experience more overheating issues than most. All sorts of problems might make your MacBook Air hot, ranging from a buildup of dust to a load of browser tabs.
