Thufir,
The best way to monitor your temperatures is using the lm-sensors 
package (sudo apt-get install lm-sensors). You can have it as an applet 
on your panel (I use a hidden side panel only for temperature 
monitoring) and your best monitor friend gkrellm (apt-get install 
gkrellm). I don't know of course if it works with Unity as I have never 
used it but work with xfce which is an excellent X-window manager.
(and of course cleaning your fans regularly!!)
My suggestions,
Joep
