CPU Temperature

Overview
Systems that freeze after a period of use (but not when started cold) may be having problems with overheating. This is especially true for laptops. You can use lm-sensors to determine the temperature of the CPU.
Using lm-senors
- Install and Configure lm-sensors
- Install the lm-sensors package (see InstallingSoftware).
- Run sudo sensors-detect and answer YES to all YES/no questions. I generally use the ISA bus rather than the SMBus bus, your choice to this question!.
- At the end of sensors-detect, a list of modules that needs to be loaded will displayed. Type "yes" to have sensors-detect insert those modules into /etc/modules, or edit /etc/modules yourself.
- Next, run "sudo /etc/init.d/module-init-tools". This will read the changes you made to /etc/modules in step 3, and insert the new modules into the kernel.
