Generally a CPU will run at 55-80 degrees but will give serious errors
85-90 degrees is where it starts to fry.

The cooler the better: add 60 or 80cm casefans and PCI slot fans if need
be. Sometimes you even need to use round ide cables to improve case
ventilation. Blowing off all the dust from the system and inside the
power supply is also a good idea.

These measures can drop CPU temp dramatically. Sometimes just adding a
few fans can give you a drop in 15-20 degrees other times the difference
seems minimal.

An incorrectly placed CPU fan/heat sink will also cause excessive heat.

Also check CPU voltage to ensure it is according to specification.
