What the original quote referred to is that as a conductor heats up, the
resistance increases. Basic physics/electricity.

If the CPU continually increased in temperature, of course, it would be true,
but then your CPU would be a puddle of silicon, etc. Of course, that's not the
case at all. Never was that way that I'm aware of.

Since modern CPU's heat up so high, so quick, this isn't a factor. I can recall
testing many a 286/386 where _only_ a test done in the first 3-5 seconds would
give you the highest CPU performance index. After that it leveled out, and never
would give you the very best index again until you shut it off for quite a while
and let it cool all the way down.
