Well as long as your GPU passes all the essential stability tests W/O crashing or Artifacts along with playing games correctly then yes. Your settings are fine. As far as temperatures go the only way to lower those on a video card are to manually increase fan speed through CCC. Proper case airflow also helps keep GPU temperatures in check as well. The only other thing beyond what I suggested is to watercool the card; but I doubt u wanna go through that.
