Thanks! I have considered this cooler.
Judging by the photos on their site it would be cutting it awfully close (looks like its as tall/taller than the wifi ports).
Even if it did fit, it would sit very close to the back panel potentially generating some whirring sounds. Also given the fan's location, I would probably have to cut some more slots in the back panel for airflow and I like that the dell cooler will work with the current vent slots.
Lastly, I've already thrown too much money at this endeavor
so I think I'm just gonna run with this dell cooler since I know it checks all the boxes.
