Temperature sensors in the Gnome panel
Most recent harddisks (with "S.M.A.R.T." technology) have a temperature sensor. Typically the CPU and the motherboard have one as well.
(all steps as root):
- install the following packages:
yum install lm_sensors
yum install gnome-applet-sensors
yum install hddtemp
- run system-config-services, and enable the services hddtemp and lm_sensors. Start both daemons as well, and save changes
(run yum install system-config-services if you don't have it installed).
- edit the file /etc/sysconfig/hddtemp to read: HDDTEMP_OPTIONS="/dev/hda"
(you can of course put a different drive number, or more than one)
- right-click your Gnome panel, select "Add to panel", and pick the "Hardware Sensors Monitor"
- right-click the sensors applet that now appears, and select "Preferences": here you can pick the sensors you'd like to see, select Celsius/Fahrenheit, etc.
