Some of the MacBook Airs do not even have a fan; regardless of that it is well documented that Apple lets their systems cook themselves to death even before they kick in the fans. I watched a video a while ago that Louis Rossman (Rossman Repair Group) showing a MacBook nearly frying itself before it even spun the fans a little.
Just a little more context on the Apple side of things paints a different picture.
As a side note, some of the repair videos that dive into the root causes of failures of Apple products are astounding given the amount of money/engineering they spend to make their products.
