Exactly!
Thats why I mentioned the peltier element just prior to the fansink
;-)
http://www.melcor.com has a variety of them.
One HD I own is spec'd at a maximum of 50C operating temperature.
Considering the ambient air temp was once that high in phoenix (june
92?) and often exceeds 45C, its likely that a trunk would often exceed
50C ... the big question is:
How hot can the drive get when its NOT powered up?
