i have a xp2100+ processor but i think it is maybe a little hot.
im without clue with those temperatures issues.
i beleive it exists different temperatures.. from the cpu, the memory, the motherboard and maybe also the hard disk and the graphics card.
The way to tell if your CPU is too hot:
1) You smell something burning and you can no longer get to POST. You take the heat sink off the processor (when the computer is off) and notice scorching around the raised central part of the processor (the die). In this case you have a dead processor.
2) You're having random lock-ups that go away when you have your case opened up (and thus have cooler air circulating over your heatsink). In this case you need to increase airflow through the case and/or remount your heatsink (only if you know how to do this correctly).
3) You have NO problems with your computer whatsoever, but you still smell something burning. In this case, something in your house is burning and you need to check the toaster, oven, curling iron, stove, etc. and possibly call the fire department.
