try this first:

and if you do not have any problem (like me!):

refer this guide how to install coretemp module.

http://www.question-defense.com/2010/03/24/lm_sensors-on-cent-os-5-4-how-to-get-and-install-the-coretemp-module

finally:

coretemp-isa-0000

Adapter: ISA adapter

Core 0: +54°C (high = +100°C)

coretemp-isa-0001

Adapter: ISA adapter

Core 1: +49°C (high = +100°C)

In nicer look:

[root@linux lm_sensors-3.3.0]# sensors |grep "Core"

Core 0: +39°C (high = +100°C)

Core 1: +36°C (high = +100°C)
