from what is see , yeah it seems to be that hotspot issue ..
if you want to do some more tests to see how this reacts:
are you running last drivers etc ? just try maybe to uninstall them with ddu and reinstall
then are you using a high refresh rate monitor ? try to set it on 60hz
try to use hdmi if you have one ..
you can always try that vertical/horizontal thing , but in all case you shouldn't not have 110° except with some airflow problem ( but even your power draw is only 330 so ... and gpu temp not even 70 .. so, sadly...)
