Fan & Heat Sink on backside of Herelink AirUnit

Hi,
How works the heat dissipation in the Herelink Airunit 1.1 ? Can the Airunit be cooled as well on the bottom side as on the default top side?
We would like to mount the airunit with bottom side on another heatsink (combined with fan) and remove the default fan on top side and access to the ethernet port. See attached draw.
Thank you. Kind Regards.
