I know this is invading ESP-land but here is a cronjob I setup in the Peachtree office,

2,17,32,47 * * * * test 32 -le `sysctlrd -p | grep "air temp" | awk '{print $5}' | awk -F. '{print $1}'` && echo "Overtemperature condition in Peachtree Lab" | Mail -s "Overtemperature in Lab" zwrite@peachtree.sgi.com

Something similar can be created for the O3K. This real example sends email if 32C is less than the reported temperature.
