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!)
