Hello Teams!
Matt Crossman here from ebm-papst Inc. in Farmington, CT. Your assumptions are correct, the "ICE" Cube is for cooling the RS-5XX and RS-7XX Motors.
Though it may not be necessary, as an alumnus of FIRST I have first hand experience with these motors burning out when run at too high a speed for extended periods of time, or when run in a confined space.
Instructions for using the "ICE" Cube can be found
here.
As of now the only way to acquire extra "ICE" Cubes is to contact ebm-papst Inc.
