Take note of the fact that drives (I'm assuming by 'drives' you mean
'spinning rust') often have much longer lifetimes if they are kept
cool.

You may want to find a way to rig a fan to provide some airflow over
those drives (it is amazing how much difference even a small airflow
will make).

For noise abatement on the fan, one of the easiest ways to reduce fan
noise is to run a 12v fan on 7v.  Most of them will start and run (at a
much lower RPM) on 7v.  And you get 7v by connecting the fan positive
to the PSU 12v rail and the fan negative to the 5v rail (if you have
'spinning rust' drives then you have 12v and 5v supply rails for the
drives).
