Update: issue resolved. Thanks to the fine folks at the ElRepo project who backported coretemp for use with CentOS 6, I am now able to successfully read the temp sensor on my i3-2100. Here is the request for enhancement: http://elrepo.org/bugs/view.php?id=181 Also more detail on this thread at the CentOS forums: https://www.centos.org/modules/newbb/viewtopic.php?topic_id=33061&forum=55 I also installed the backported w83627ehf driver from ElRepo which worked with the Nuvoton chip on my Asus board after adding "acpi_enforce_resources=lax" to the kernel boot options in grub.conf. I can now read the board's sensors on voltages, fan speeds, and temp readings.
