I forgot to mention that there is an air intake on the side of my case
where the drives are, so it's perfectly possible for room air to blow
across the drives, thus reducing their temperature to something closer
to the room-ambient temperature (which is about 23-25C right now) and
lower than case-ambient.  Good airflow across hard drives is vital to
their temperature and thus life expectancy.

Not that any of this is at all pertinent to the conversation.  But the
original poster asked what a good operating temperature for a hard
drive was and I answered that.  The construction of my personal system
is largely immaterial.
