This is a good point too, I actually just did this on my xps15 as well as
they are known to be badly thermal pasted from the factory, and some years
later, same thing as Stephen described. That wasn't too bad, redid the cpu
and gpu with high quality stuff, and allowed me to do some mods with
thermal tape some of the mosfet chips to the case others found works well
too.
This could be your cpu or gpu here that use large heatsinks.
I also had a heatsink once pop off a southbridge on my mobo too that caused
some havoc, and once on my dell server raid, thinking about my adventures
in computing over the years.
Moral of the story, heat kills.
