Hi mate, not sure if this is right this temp. I have mine MSI 970 Gaming Edition overclocked and never going more then 64C with auto fan, fans never spin more then 42%.
My settings on MSI Afterburner :
- Core Voltage 0
- Power Limit (%) +110
- Core Clock (MHz) +200
- Memory Clock (MHz) +500
- Fan Speed (%) Auto
This settings give me Core MHz on 1655 and Memory MHz on 4005 all stable. Just play with this card and check temps, all I know is this card on stock and overclocked NOT should run that hot, check reviews on YT and see other peoples. Can be problem with thermal material inside not sure. If you running games on 80C I will send back and replace for new one.
Good Luck
