I am not sure whether I have a defective unit, but my surface pro 3 is already heating up right out of the box. When I first got it, it was not doing this. Today I went on wifi to get it updated, and during the process the surface seems to be exploding. It is very odd, because when I press the power button it becomes silent, but when I turn it back it the fan goes wild. I may have to get this guy replaced.
