I use a dell e6420 as my daily laptop/workstation. It stays docked and
on 24/7 while at home, often running multiple vms or docker containers.
I've not experienced what you have described. The laptop does get a
little warm during certain video conference meetings, I do not have any
thermal shutdown events. I would check for fan function and speed, then
firmware for possible related updates.

If it helps, my specifics are (according to dmidecode):

        Version: A19
