Edit: I found out from looking into the post from coffeeturtle that not all motherboards support WMI temperature reading. You have to explore the WMI namespaces for your system! I (stupidly) fried a computer. It was an old Zotac small form factor device that was junked at work, so I turned it into a home theater PC. But I had put it in my "audio rack", which has glass doors and not very good ventilation. Normally I would open the doors while it was running and I use a media remote which would hibernate the system. At some point, it woke up by itself (probably Windows Update) and did not go to sleep again. Unfortunately this happened during the summer months while I was away on a small holiday and of course the glass doors were closed. When I finally noticed the system was on, it was super hot and the fan was at full blast. Dead. No POST, no green light on the mainboard even with a new power supply, old mechanical laptop hard drive gives errors when connected to another device. My next home project will be to make some appropriate ventilation in the audio cabinet. For the replacement I bought a used HP ultra small form factor machine and decided to start working on an app to monitor the ambient temperature sensor on the motherboard and shutdown the system if needed. I used some code for smooth label updates from here (needed updating to work with latest AutoIT) and temperature conversion from here (not really needed, only if you want temperatures in something other than C). Maybe I will work on this some more and make it configurable with an .INI file or even storing the settings in registry, but since I probably won't I thought I'd put it up as an example of what a non-expert can do with an afternoon of coding and ideas from the community here. This uses an ambient temperature sensor populated on HP machines in HP-specific WMI extensions but the WMI query can easily be changed to any available sensor including CPU or GPU. The watchdog monitors temperature, warns with S.O.S beeping if the set point is exceeded, and either shuts down if a timeout is reached while the temperatures are high or goes back to monitoring if the temperature goes lower then the set point, and logs events to the Windows application event logs. The GUI it puts up is very small at the top center of the screen (very small on a 4k display anyway). #requireadmin because of the WMI query. A timer for the WMI query because of prior experience using similar functions in WinPE to get model infos from HP WMI bios extensions. If you play around with this, please post your fixes/improvements/changes back to this thread. Have fun!

I couldn't resist making a S.M.A.R.T. script using WMIC. It gave me something to do over the holidays. 1) This will only give SMART data for the main drive. (ie: C:\) 2) It will most likely Not give data on Raided or USB drives. 3) It only shows pertinent data columns and ignores all others. 4) It should be good enough for a quick glance and an example how to parse WMIC output.
