2 general rad cases; higher airflow resistance (2 core) and lower (single core)
- 2 core selected for performance, more powerful fan
- single core for lower noise, less powerful fan

is either rad configuration 'better' than the other ? (to establish an air flow reference)
seems that the air flow pressure range would be greater with the 2 core/more powerful fan combo
2 rad cases fine

I assume fans are 120mm X 25MM?

When I do fan comparisons on homologous fans I like test them @ equal RPM vs. Volts. method, if there are diff. in performance it is quickly apparent.
