I'll tell you folks upfront that the Big Momma does outcool the Black Ice and definitely the Cooling Cube. The Momma is a modded radiator for a car and the Cube I reckon is a refrigeration type unit.
The main consideration in the Black Ice's inception is primarily space, aesthetics, weight (shipping), mounting options; and balancing this with performance and other functionality did lead to some sacrifices in terms of its girth and performance.
However, being the biased guy that I am
, the Black Ice has a substantial headroom for the kind of cooling which you wish to implement. You can put as much as 400W of pelts to cool and you would be humming along just fine.
