That doesn't look like a CentOS kernel.

Not sure what acpi thermal info might be returned by your system (try 
looking in /proc/acpi/thermal_zone), but as it's an Intel Core based 
processor, coretemp should return basic CPU core temperatures.

You can install the coretemp module from elrepo.org (kmod-coretemp) 
which should also pull in an updated lm_sensors as a dependency from the 
same repository. BTW, it will only work with kernels that are kABI 
compliant with the upstream EL5 kernel (i.e, the CentOS 5 kernel) - no 
guarantees it will work if you're running a custom kernel, you'd need to 
recompile the package against your custom kernel.
