You could try removing the shell of the cooler of your card.
Cut a 12cm hole in the side of Case and put there a 12cm fan or leaf the Case open.
insert a bit of foam or something between the cards to force them apart.
Alright so I have the following rig:

Case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811112300
I replaced a 5830 I had in it with 2x 6870's in crossfire. I use it for gaming and mining. Unfortunately I noticed that the first video card (closest to the cpu) has very little space before the second video card slot. The air intake must be affected because the first card can easily reach 103~ C. I'm not sure what to do. Currently, I have the rig right next to the AC unit and the cold air is keeping temps at 80C & 57C respectively. I can't have the AC blowing 24/7 otherwise I'll get pretty chilled but I'm scared to run both cards with the temps I've seen. Any ideas? I don't think the case is the problem really. There's plenty of airflow in there. I think the fact that the pci express slots are so close to each other is what's wreaking havoc on the one card. The other card has about 1-2 inches of space before the case wall and does just fine cooling itself off.

If you are running Windows (which I presume you are since you have mentioned crossfire), please download MSI Afterburner software. Then a) Lower the memory speed to 750MHz b) Try to lower the voltage to 1.05V and simultaneously bring down clock speed to 600MHz. and check the temps.
