I did a little measuring and some quick math, the air flow of the fan is the only guess but at a minimum it should require 1/8" or 3mm of clearance all the way around to provide the right amount of airflow on the sides to the device you are placing next to it, so an FC6 in this case.
The bottom side FAS has provided for a little better than 5/16" or 9 mm of clearance from the fan opening to the floor of whatever you are placing it on which I would not violate.
