Here’s an alternative for you.  Install Hardware Info64 (HWiNFO).  Within that tool on the “Alerts” tab you can trigger a batch file when a sensor exceeds a boundary you define.  For instance, I have it set to send me a text message (via BLAT) whenever my GPU temperatures fall below 30c (which means they are not working).

The batch file could also trigger the “shutdown /r” command.
