Whilst you don't want your drives overheating, I wouldn't worry too
much about them becoming too hot, most drives are comfortable
operating with temps that many people would consider too high.
Just had a quick look at the datasheet for the Hitachi 2T drives I
use, they have an operating ambient temp range of 5 to 60 degrees
C, which is fairly wide. I'd be suprised if your case temp gets any
close to 60 degrees. (Hot water from my hot tap tops out around 55 and
I can't put my hand under that for long.)
Also, there's some evidence to suggest that higher temps aren't as
important in drive failure rates as often thought.
I wonder how much energy would be saved if the worlds datacenters just
operated a few degrees hotter. (and stopped cooling dead underfloor
space, but that's another issue.)
