Adding to and expanding on Hugh's advice;

Dust can block the exhaust fan or the CPU fan could have failed. Every 
Thinkpad has a service and parts manual available on the download page 
that has detailed tear-down instructions. This will help you 
tremendously when it comes to clearing the fan and/or replacing it.

If you have support in the hardware, install 'acpi' and then run 'acpi 
-t'. That will show you the temperature on the CPU (and other thermal 
sensors). From there, it should be a pretty easy task to hack up a 
script to parse it's output periodically and record the temperature to a 

Let us know exactly what make/model you have for more help.
