That's way too hot.. I'v got a pentium 4 2.0a and when I'm using it it usually doesn't go above 46c.
You really should check into it, maybe your heatsink is not on properly? Is it a retail intel heatsink? Perhaps you should get another one..
Also, I used Arctic Silver thermal paste instead of the thermal pad that comes by default on the bottom of your heatsink. It really works great, and it's like $6 for a tube that has enough for like a dozen builds.
