setting high temperature threshold before server self reboot

[sunhux G]

Is there any way to increase the threshold before an RHES 4.x self reboot?

And is there any command to check this threshold temperature & the current
server's temperature so that I can write a script to alert me before it
reaches
the threshold & reboot (which will cause service disruption) :


Below are messages log showing high temp which has caused one outage
