I just wanted to make sure that I've placed my two 6990s in the corrected slots on my motherboard.

I have inserted 1 6990 on the top pci slot (bottom left, top red slot with a battery directly below it) and another 6990 in the slot two below it.
I did this to maximise air flow as the 6990 in the first slot was getting very hot due to lack of airflow.
Is the positioning correct?
Also, in some games, I get a higher performance when CF is disabled. I have posted two videos on YouTube. Of the same game, with and without CF enabled and I got a higher fps, why is this!? The computer is detecting 2 6990s.

The specs of my machine are in the YouTube video.
I know this is a long question, but I really need help as I believe that I may have wasted a lot of money on a second gpu.
Thank you.
