I have an old Dell Precision m4600 laptop. Big, bulky and heavy, but cooling is excellent, even though it has air intake on the bottom. Discrete Nvidia GPU running at full clock (because of an external UHD display) and temperature constantly about 60 degrees Celsius. And cleaning the fans/heatsinks is dead-easy and can be done in 10 minutes. Do newer MBPs have those overheating problems solved? I was thinking of buying one as my next laptop.
