I've yet to own a laptop that had acceptable temperatures out of the box and/or second hand purchases. My knowledge was built on desktop building and converted over so I suppose my perspective is a little different with wanting to teardown everything to see what I'm working.
Even the y510p had horrid Temps, same with my m11x r2, g53, g46, k53sv the list goes on lol
Your right though, absolutely right. I just don't expect decent support from vendors so I'm OK with teardowns
