My favorite test is cerberus(ctcs). Quite a few OEMs out there
use it to burn in their systems. For me it can typically find a problem
within a few hours. Whereas memtest I've let it run for a week and have
it not find anything useful.

Though the results of cerberus sometimes won't help you pinpoint the
problem(often the result is just a machine crash). But at least you
know there is an issue and can start swapping hardware until it's
fixed(or just replace the whole system).

Have you checked to verify that the fans are spinning?

Since it is a new system, I think you should take it back to your HW
distributor and have them run cerberus(ctcs) on it, as Richard Karhuse
wrote.

If it takes a few days for it to get the Kernel Panic, I doubt that is
related to the OS.

Let your HW distributor do the work of troubleshooting and replacing
whatever component(s) are faulty. They can get a CentOS Live CD and
run that on it.
