Interesting. I try to run smartd anywhere it's supported and have
appended the last few entries before things went sideways; 60° C/140° F
is a bit toasty!

This system is a couple of years old, might be time to blow the dust out
with compressed air and see if the bios has more aggressive fan settings.

Is the Raw_Read_Error_Rate changed a problem?

(Thanks!)
