yeah there do tend to get hot mate. Best thing to do is make sure it isn't in a confine space so it can send out all that hot air.
I was on mine the other day and gotta temp thingie in my room and the room went up from 17c to 24c in the space of 3 hours, plus my lcd will also pump out some heat to.
on the plus side come winter it will save on the heating bills
