Well if they are like me, I'm taking the HSF off on a regular basis. Always trying to fing the best air cooling method. After several times of repeating this, my Duron looks like sh*#. But this puppy keeps going even with all the chips to the die. I do recall that if you want to really toast the cpu, don't put the orbs on designed for the celly. I did that once awhile back when I was new to this game. But once I started in these forums its a cardinal rule now not to attempt it. Now I have settled with taisol, I don't think I'll be removing anytime soon.
