Hi - got a 17" i7. Noticed recently that the PSU runs really really hot, but that did not worry me too much. What does concern me is that the magsafe plug is getting almost too hot to touch - no exaggeration. And when I do remove it there is a very faint burning smell on the plug.. When it is like this, I also notice that I only have to touch or knock the plug for the light to go out - screen dim as if unplugged - and then come back on again after a couple of seconds. I am going to take this into apple, but sometimes it take a while to get up to this temp and are concerned that it won't do the same thing at the genius bar. Anyone else come across this?
