you probably got an air bubble in the grease, it's easy enough to do. remove the heatsink, wipe off the old grease and try again. one method i've used, is to put a smooth line of grease on one edge of the chip, put the heat sink at an angle about where it goes touching that edge, and then rotate it on squeezing the grease towards the far side as you rotate the heat sink on. also of course make sure all of the clamps are on. a cooler heat sink is a sure sign of trouble, you know the chip is getting hot, and that heat needs to be moved to the heatsink so it can be dissipated. also remember to use the grease sparingly, with my trick you should press/squeeze hard enough to press out most of it as you rotate the heatsink on, you can remove the excess with a q-tip etc. but it shouldn't be a problem if some is on the edges. you should see a little squeeze out on the 3 edges other than the one you applied it to. now you see why the film is so much easier in manufacturing. definitely check the temp immediately after you power it up again and if it's remotely that hot shut it down immediately before you cook the chip, 100c is too hot and you risk permanent damage to the chip, which in some cases will also make it hotter. are you sure you got grease on the processor? at least on some machines the cache or bus interface chips also touch the heatsink, you'll want to grease them all.
