It more than crowds the fan --- it obstructs it, bottom line, no sugar coating that. I ended up keeping the "part E" PCB cover removed, and took a dremel to the adapter's edge where that plate cover usually screws back in. Otherwise, the fan had a large amount of tension on it, and isn't really able to truly seat into the Ciiicooler properly.
You'll get crazy rattling going on with a Ciiicooler SHORT unless you trim things down on this adapter, print the non-short model, or redesign the short version's mounting hole location.
