Take it seriously.
If it is "hot almost constantly" you should take a closer look at processes run
over some longer period of time (top, iotop, ...; you can run them as a cron
job and collect data as well).

- System-Preferences-Power Management
- man hdparm
  # hdparm -I /dev/sd?
- $ yum info hddtemp
- Gogle search: linux hard disk temperature
