I've been running 4x ODNO for a couple years now.
Temps did not increase significantly over 1x set up, I can't remember the numbers off the top of my head but I believe it was about 20F at the tubes measured with an infrared thermometer.
Overall, I think that the temps in an open ODNO fixture(even at 4x) would be far lower than in a closed normal output fixture mounted in ceiling with no airflow and diffuser installed.
