Yep . . .
It depends what you are running as well. I run ITV Player (in UK) and the fans kick in and machine gets very hot when I do, the GPU must be located there as well?? My machine was fairly cool in comparison to my wife's but when I replaced the HD on her machine it ran far cooler, awkward but not difficult to replace. I've just replaced my HD, we'll see how that gets on. I checked out all the Mac i27 inches in local PC Worlds at that time and they all could fry an egg. Later versions seem better.
HTH
