My work mac never seemed to overheat itself, but it would routinely be warm and out of battery when I took it out of my bag if I wasn't very careful about what was running when it went to sleep. If Outlook was left running, look out.
It is amazing that "goes to sleep properly when I close the lid" is a competitive advantage for a laptop in 2024. My X1 Carbon would bake itself in my backpack all the time but my new work mac has been perfect so far.
