Yes, they seem to update only on application restart for some reason but it seems they cap at 77C on furmark and round the same ingame. Also see how the game behaves in the pic. only 61% gpu usage under 60fps, same behavior in 3 of the games above. It's strange tho that the VRM hits 80C while gpu is at 60ish %. But why only in some games, i don't understand.
UPDATE: Trying to stress vrm as much as i can, reached 85C seems to cap at that temp, hwinfo is saying performance limit - relaiability voltage "yes"
