Since the elrepo kmod-k10temp/lm_sensors packages worked, then you may
also benefit from the elrepo kmod-powernow-k8 package.

With AMD Phenom II quad-cores running centos 5, kmod-powernow-k8
typically gives a 8-10C drop in core temperature at idle and a
significant reduction in power consumption at idle as described in this
centos bug report:


You will also likely notice that your cpu fan slows down at idle. It is
worth installing the kmod if just to quieten down the cpu fan.

As per the bug report, this issue should be fixed in rhel/centos 5.6
