This post shows how to update a server's Baseboard Management Controller (or iDRAC or maybe an iLO or something else) to power the server off at a different temperature threshold than the manufacturer default. This is done using ipmitool and freeipmi commands. We use it to lower the set points for some of our servers in a less-capable room that we have. The servers will then do a hard shutdown if the thermal threshold we set is reached.
