My GTX570's are using the stock coolers and running on a 750W power supply, so you should be fine with your setup as well. Nvidia has done a good job of tweaking the cooler to run efficiently and quietly. Of course, you are free to tweak the fan profile as you please with MSI Afterburner and the like, so rarely do I ever see my cards hit 75C.
For what it's worth though, I do keep my cards separated by putting the second card in the last PCI-E slot since my case allows outward airflow due to perforations below the last PCI slot. Your experiences may vary if you sandwich them together, but I can't imagine it will be by that much.
