years ago we had a computer that used a Fairchild (Intergraph) Clipper chip.
after it arrived it was worryingly unreliable: lots of transient faults and lockups.
it turned out that the clever cooling system the computer maker used was
just far too efficient, and made the box too cold.
the chip didn't work correctly when it was too cold.
(no one thought to include an ``it's an ice age'' alert.)
they restrained the cooling system and it was then ever so reliable.
probably.
