If the readings of around 100 degrees C are accurate, this is too hot for
a processor die. While you can run power semiconductors that hot and
still achieve acceptable reliability, this is not reasonable for a
package like a processor. The primary failure mode is bond wires
opening, and it is strongly temperature dependent. A typical power
device has 3 bond wires, while a processor has several hundred, so the
overall failure rate for this type of package gets too high at a much
lower temperature.
