But VMS side work is still the most fun I have.  And it is a customer
system so we're helping a customer (who likes VMS and wants to stay on
it).

Fan test shows the wonky sensor does respond to ambient changes, and
more or less tracks with the working one.  A fan aimed at the front
panels dropped the logged temperature on both units by the same amount
(4 - 5C).  If the warmup test does the same then we'll just set the
thresholds lower on that system's checks, and if needed add a power-
off shutdown at XX degrees C (to be determined but around 22C lower
than the working system).  Easy peasy.  We've had to do a hell of a
lot more to keep various wintels running reliably over the years.
