Yeah, reducing heat output and fan noise should be more of a goal for mainstream PC vendors. My ThinkPad X1 Nano is a lovely machine… super lightweight, tiny, solidly built, decent keyboard and screen, but it starts getting hot and spins up its fan with the slightest hint of work. I have to keep its CPU throttled by putting it in power saver mode to keep its fan off (most of the time), which brings major performance tradeoffs.
