I don't think that's too bad for temps really.
Edit: disregard what i typed below... misunderstood your case airflow . Could try a similar experiment with your radiator fans though - would give you an idea of case pressures.
Might be an interesting experiment to unplug the front intake 140 and see what happens. Left without power, the direction it spins will tell you if you are hindering airflow through the radiator.
