I have a DELL R710 that intermittently gives the following errors within CentOS release 6.3 (Final):
Mar 24 11:43:04 swamp.mail.uwo.pri kernel: CPU10: Core temperature above threshold, cpu clock throttled (total events = 1)
Mar 24 11:43:04 swamp.mail.uwo.pri kernel: CPU22: Core temperature above threshold, cpu clock throttled (total events = 1)
Mar 24 11:43:04 swamp.mail.uwo.pri kernel: CPU22: Core temperature/speed normal
Mar 24 11:43:04 swamp.mail.uwo.pri kernel: CPU10: Core temperature/speed normal

Mar 24 11:48:05 swamp.mail.uwo.pri kernel: CPU18: Core temperature above threshold, cpu clock throttled (total events = 64905)

Mar 24 11:50:24 swamp.mail.uwo.pri kernel: [Hardware Error]: Machine check events logged
{noformat}
The errors have been happening intermittently for about a week, sometimes the errors point to CPU 6 and CPU 12.
When the errors happen, there is no error display message on the server, nor is there any indication of a failure (except the above error message) and operation continues as if normal.
Flashed the BIOS up to 6.4.0 after the first error and no change.
Ran full diagnostics on the machine with no errors.
Opened the machine, inspected the fans, airflow etc and there appeared to be no issues.
This server doesn NOT have Dell Openmanage installed and we are in the process of installing it.
Any thoughts or suggestions appreciated.
