Depends very much on the enclosure. Plastic without fan is definitely
not enough. Aluminium with large contact surface might be enough for
7200 rpm if case fans draw air trough it. Depends on the design,
no general statement is possible (as so often). One method of
finding out is to get one, use it heavuly and measure temperature
via SMART while doing so. If this is still o.k. according
to the manufacturers documentation (e.g. Maxtor: <=55C) and
when adding the temperature difference between the time you test
and the maximum ambient temperature to be expected, go with it.
Personally I have airflow on all my drives, just to improve
reliability. But I do not have any drive bays.
