The System Temperature plugin has a one-third output on my MSI 970A Gaming Pro Carbon. The MB temperature is reading 7 degrees C which would be astonishing if it were true. The more likely scenario of 21 degrees C (room temperature) would be more likely.
I've uninstalled/reinstalled the plugin, removed/re-added the MB drivers, and there's been no change. Anything else I can do to get a proper readout?
