You want the package "lm_sensors" installed. Then:

1) run sensors-detect (as root, of course) to record the sensor hardware on 
  your motherboard
2) enable the "lm_sensors" service (chkconfig lm_sensors on;service lm_sensors start)
3) run "sensors" to see current sensor data

If you use gkrellm, it has the ability to monitor the sensors. You can
also run a cron job, if desired.

I'd suggest you run gkrellm, and set it up to monitor the sensors.  Then you
can get a good sense of the correlation between cpu usage and cpu temperature.
