That's in the firmware. You may, or may not, be able to do something with
ipmitool, but I don't think so. Reboot, and look in system setup. It may
be under performance settings.

Warning:I'm new to CentOS and have not tested the suggestion below (with
Linux). So please research if it sounds like a good idea.

It may be worth trying to bypass the issue by installing VMware ESXi and
setting up CentOS as a virtual machine.

This will give you additional control and backup options for the system.

or maybe try fancontrol from lm_sensors package?
