not sure if this'll work for you but..

cat /proc/acpi/thermal_zone/THRM/temperature

You can add the applet to one of the panels to keep an eye on the temps. if you want.

Here's a short version of installing them:
Just open a Terminal (Applications -> Accessories -> Terminal) and type (or copy and paste):


sudo apt-get install lm-sensors sensors-applet hddtemp

Next, run sensors-detect. Answer y to each one until finished.

sudo sensors-detect

Now you can also run

sudo hddtemp /dev/sda
Where sda is your hard drive.
and it will show the temperature of your hard drive if it can.

All temps. are in Celsius by default, but you can change it to F or Kelvin if you want.

adding hdd temp to sensors-applet


gksudo gedit /etc/default/hddtemp

Make RUN_DAEMON="true"
Save and close
Finally, restart to load all the sensors.
Once back at the desktop, right-click on the top panel and choose "Add to Panel.
Select "Hardware Sensors Monitor" and click the "Add" button, then "Close".
Right-click on all the sensors applet that appears on the top panel and choose "Preferences".
Click the "Sensors" tab. There you can select/de-select all the relevant sensors and adjust their low and high values as well as set alarms if desired.

Time to go eat.

Not on Lucid. thermal_zone is empty by default.

you can also use conky for constant monitoring. Here's the .conkyrc I use, monitors temperature in Celsius:
