The only important aspect is probably to do with heat/noise in your server in the first place.
I would think lack of proper cooling might contribute more to premature death as well. However, I remember reading something a little while ago that even excessive cooling can kill them prematurely as disks are designed to operate within a certain temperature range. Of course, just because it's out there doesn't mean it's true, but it just goes to show how inexact of a science this really is. I'd say just do your best, within reason, and hope for the best (while making sure you're doing proper backups).
