No argument here.

I'm suspecting it isn't good for anybody -- my guess is that
the expected failure rate for any 2.5" HD will shoot up in
that environment.  The ambient temp was 55 deg F, BTW.

Hey, a fan is just another moving part.  I suspect that *any*
airflow at all (thermosiphoning) would alleviate the problem.

Anyone remember MacChimney?

Yep.  Maybe the 1U rackmount case will be better.  Meanwhile,
I'll run with the case off (my guess is that the HD is about
40-50 deg F cooler now).
