Hmm what were the results of 2 top intakes versus one blocked off? I understand now that you want to control the direction of the airflow through the case but if you just mounted a low / moderate CFM fan wouldn't it not interfere with the HS airflow.
This is where a low ceiling case can produce a wind tunnel effect. You're pushing air from the front of the case to the back with the cpu heatsink standing in the way, where it benefits from the breeze. Putting a fan in the rearward top position can actually interfere with front-to-back airflow.
This approach is not helpful with a high ceiling case. With a significant space between your heatsink and the top of the case you can't really get that straight-through airflow that a wind tunnel requires. Instead, you have a system that acts like a bagpipe. In such systems, if you have both positions filled with intake fans you will get superior results.

Scythe Slipstream 800rpm
I agree. I started with a prejudice against Slip Streams. But the more I used them the more impressed I was. Now I am a fan of Slip Streams.
I only want to see two changes: an FDB bearing in place of the sleeve bearing they now have, and a change in name to 'Slipstream.'
