I have a 8 hard disk enclosure which was working well for several years but whose fan seems to have failed during my last shutdown. I didn't realize it and ran several hard disk intensive backups for a couple of days. A slowing system got me motivated to investigate and I got a serious shock when hddtemp reported temps of 90-98 Celsius and nearly burned my hand trying to remove the hot-swappable drives.
Amazingly, the drives still seem to be functioning in the enclosure (with a new fan) but I am going to be getting replacements just to be sure. How long do you think I can run the drives before they finally go kaput?
SMART output from the hottest drive (see the airflow temp field) :
