Is Crossfire viable for me?

Need a little advice. The 2 pictures above show where my case is and how amazing the air flow around it isn't... I'm looking at upgrading soon and I wondered if I would have problems keeping 2 7970's cool enough.

I don't have any side fans as I use the windowed side for my case. At the moment I have a reference 7970 which idles around 40-45 degrees. At full load it gets to around 70-72, I know this is to be expected from a reference card. I O/C it to 1000/1500. My i5 idles around 30-35 degrees and doesn't exceed 70.

The PC sits directly on the carpet and I haven't had any problems with dust or anything. If I was to add another 7970 to the PC which model would complement my reference card? Or should I be thinking about a 690 or 7990? Or am I worrying about nothing?

Thanks for taking some time out to help.

Sorry mate but what am I looking at here? Air comes in the front of your case and goes out the back and sides so dont push its back against a wall and keep the front end away from a radiator! Turn the case so you are looking at the front rather than the side in the first picture. Other than that put you ref 7970 as the second card as it exausts out the rear of the case so the hot air is not heating up the primary card.

I have that case, its a nice case but its crap for cooling a multi gpu setup. Your best bet is to stick some fans on the side mesh and lose the fancy window. If you have exhaust type gpu's stick four 120mm fans on as side intake. If you have radial type gpu's that dump heat in the case stick four 120mm fans on as side exhaust and make all your other fans intake.

Thanks. Sorry for the crap pics. At work now but I could try turning it around. That would give be much larger gaps. Just need to make sure I can sit comfortable. I am just worried that the airflow as it stands is poorly affected due to minimal gaps between the PC and the desk surround.

Seems like the way to go. I hope I kept the mesh grill somewhere...
 
I have the same problem where my desk is so my tower is up on top to my right. One plus side is if I ever need to tinker (and we all need to tinker!) its easy to pop the side panel off.
