I've done some more testing and, while use as a (full load/speed)
builder machine is a no-go, it looks like this 4-core G5 can
still be used for boot testing and basic operation without
overheating. The prior failing machine overheated more easily
but might have a similar status if I test it just for such use.

How long the recently failed G5 will be useful for boot and basic
operation testing, I do not know. But probably longer than for
the originally-failing G5.
