Now I'm planning on a new build with a HAF 912 case. I haven't bought any of the components yet, but I know I'm going to get a discrete GPU. I know that from reviews, the Zalman fan pushes more air than the Lepa (Lepa=25cfm Zalman=34cfm (according to X-Bit Labs) ), but the Lepa focuses the air in one direction much like Silverstone's AP121. So seeing the case layout which is better for the GPU? More airflow VS. Focused airflow.
