Many laptops have bad thermals in general under load and often even worse with case closed.

true but mostly irrelevant as there rarely is any load to speak of.

if you need a heavy duty machine, use it, but most of the time you don't, that's the point.

(for comparison; skylake laptop uses about 20W under max load, my 12-gen desktop uses 40W while idle)
