I don't know of anyone who's posted about having two cards of different 580's and their cooling differences.
I myself am thinking of going SLI soon and my cards will be sandwiched so I'm learning about what others are learning about it. The top naturally runs hotter and I've read anywhere from 5-15C higher. My problem will be the top card will not be breathing any cooler air into it so close together.
I've thought about the MSI GTX 580 TwinFrozrII or Lightning would keep temps cooler if it were on top while the EVGA reference card is on the bottom. The bottom card blows the air out the back and the top MSI card runs a bit cooler normally. Might end up with better temps. It's hypothetical because I've not read anyone was running this set up. I'm thinking the open cooling on the MSI wouldn't trap heat. Natrually you'll being ambient temps inside your case higher but if it's well ventilated you shouldn't incur any problems.
Let us know what you decide and if you do go two different 580's please update your post and let us in on your results.
