Tough PIC

[Art]

You could cool one with a peltier device, but I doubt you could run it fast enough to get it hot.
PC CPUs don't have to read internal memory.
Pics are more than a CPU, but certainly Do go screwy when the outside environment heats up...

I have a 16F84A running in a vehicle that goes haywire in the heat every time (digital speedometer),
but resumes as normal when the vehicle cools down without needing any reset.
The 16F877A does not seem as fragile though (so far).

I'm still guessing it's the internal interface between it's core and internal memory that would fail.
Not that my theory could be tested. It's not like the CPU can be isolated to do anything without
using it's program memory.
