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.
