But is not that change the same as going from COLD to HOT when you apply
power to the chip under normal operation of the computer?

Not an issue as the temps are well blow boiling
(nominal 145f).
You missed the whole point. A sudden change (as in a second or so) from
65 F to 145 F will shock a chip far more than a gradual change (15
seconds) from 65 F to 212 F. It is the rate of change, and not the
change itself, that matters. With hot water hitting the chips instantly,
the rate of change is going to be *really* fast. It may also be uneven -
if a large chip only gets half soaked with the hot water at startup.
