Download and run Everest Home Edition.
Everest Home Edition
Everest Home Edition (the successor of AIDA32) is a system information and benchmarking tool with full hardware & software information available as freeware for the individual user. It comes with a built-in hardware database and physical information for CPU, motherboard, hard disks, optical drives, chipset and much more. The information can be displayed on-screen, printed, or saved as a report in HTML or text format. The built in diagnostics module can help you find potential problems, by highlighting them in the report and also includes links to manufacturers web sites, driver updates and more. An easy to use report wizard allows you to create detailed reports in the format of your choice.
The newest edition on the Lavalys site seems to have deleted the “software” reports so try the download at snapfiles. (The screenshot there shows “software”)
The newer freeware version on Everest’s site does not seem to have “software”.

Once you open the ap, click on the + to the left of the word "computer" and open the tree, then click on "sensor".
The right hand screen will give you the operating temps of various components of your system (mobo, processor, hd, and more) as well as telling you if fans are operating and at what speeds.
Keep program up and running and see if the temps change or the fans stop before your machine shuts off.
