I had the same problem with external usb drives.  While I was on 
vacation, the heat generated killed the drive  along with half of my 
vacation pictures. 
I only by external enclosures that have built in fans now.
Anything that pulls the heat away from the drive will work.  A heat sync 
on the drive wouldnt hurt either :)
