I doubt that's it, but might as well remove it from the
equation for the time being, doing so could only help to
isolate variables.

If you think there isn't enough airflow, improve that.
Whether an open case helps can depend on the case, with a
very bad case it can help a little but with a good setup it
should have minimal, sometimes even detrimental effect. You
might open it and temporarily point a desk fan at it, temp
sensors aren't *always* right.
