1. Change out the stock fans. While being quiet for a stock config they are seriously lacking in airflow.
2. Put some fans blowing out the top. This will greatly improve temperature of the air inside the box. Without top exhaust fans the single exhaust can't seem to keep up with the three intake-fans. This leads to air building up in the case as the air being pushed in by the front fans can't get out soon enough.
When I run my DCUii 780 in the open it maxes out at around 67-70c. When in the case it quickly reaches the same temperature. But then you can see it slowly rising as the air inside the case (I.e the air the card uses for cooling) slowly heats up. Making it harder and harder for the card to cool itself. This was remedied by adding two 140mm fans blowing out the top.
All in all, this case will never be as cool as a Air 540 or something, but that was never the point either.
in my testing adding more fans made it worse..
i had a corsair 140 in the front, along with my 140XL and its push pull jetflo 140s
i had 3 jetflo 120s on top and 1 corsair 140 on the back..
adding more fans and increasing flow just made a jet stream from the front to the top. it didnt really increase any air flow to the GPUs. actually i think it made it worse by making a vortex of hot air right above the gpu..
if the bottom shroud had a fan mount blowing up instead of 2 ssd caddies i think it would have helped a lot with the cooling.. btw, dont put a ssd in those caddies with crossfire.. the gpu is so close it over heats it and you get a blue screen..
a case needs a bottom fan or a side fan or both to really be crossfire/sli compatible.
