Strategies on server/equipment shutdown based on temperatures

With summer rolling around (finally here), sever room temperatures are on my mind. We have a variety of servers (supermicro, dell), with different monitoring options (BMC, iDRAC), which give us thermal stats outside of the OS.

I want the ability to gracefully shutdown the servers if the high temperature alert is tripped on the BMC or iDRAC. From reading through iDrac material, it looks like it is possible to write a script to sense the temp and then send the shutdown command. Is this the best practice? Or are there readily available utilities to help stream line the process?
