I see you got some Vornado fans on those 6990s, how big of a difference do they make versus a cheap Honeywell desktop fan? I know those suckers are strong but not as strong as those Lasko/Stanley mini carpet blower fans....It's all about efficiency at this point though

6970 I wish was 6990's

almost 10 degrees less, it's not really cooling down the card directly but moving away the heat form the areas! Make a big difference
I am going to move things around and I am in the process to change all the cards with 5830, hash/watt/$ are the best
I got inspired from some rig on the wall I am thinking to place the PSU there
