this IronPython script reads servers from a txt file C:\\servers.txt , connects to each server with the function RemoteConnect
Remoteconnect function reads the internal CPU TEMP from the WMI class MSAcpi_ThermalZoneTemperature located in namespace \root\WMI
if internal CPU temp exceeds a certian Threshold , the function sends an alerting e-mail , it can also send an alerting SMS using a modem (not included)
*settings crtcltemp depnds on your environmnet
*servers.txt contains a server name per line 
*Smtp server must support open relay from the sender ip address machine
