I have a 478 P4 about the same age. I had the heat problem until I 
mounted two high velocity case fans in the box. One in front 
drawing air into the box and one in back drawing air into the box 
and then just letting the air escape through the builtin vent 
system on the box. My idle CPU temp went from around 62c down to 
43c. Before doing this, under any kind of light work load the CPU 
temp use to jump to 69c almost instantly and under anything heavier 
it went right passed 75c. Now the highest CPU temp I have seen 
under extreme loads is about 60c. Setting fans in both ends of the 
box drawing air in, created a lot of air circulation in the box 
allowing the heatsink to cool better so it would draw more heat 
away from the CPU like it is supposed to do. End of heat problem.
