Has your laptop always run this hot? It could be a manufacturing error: either too much or too little heat transfer compund between the die and the heatsink. There should be just enough to fill any air gaps between the die and the heatsink, but no more, as HTC doesn't actually conduct heat very well (better than air, but not nearly as well as metal). If your laptop is out of warranty and you're feeling adventurous, you could open it up, carefully unclip the heatsink[*] and pry it loose, wipe off the HTC (use isopropanol if necessary) and apply a fresh layer. [*] most likely copper blocks on each chip (CPU, GPU etc.) connected to each other and to a heatsink by copper pipes.
