As I said earlier, Beta and PTR are using the same client, and everyone has access to PTR, if you want to test how this will affect your system, you only need to download about 250-300MB (out of 20+GB) to be able to enter the game and test this. If you already had the PTR client recently updated, just go in and get it patched, it's a small patch.

Do you have your frame rate capped? What were you getting before, what are you getting now?
Ultra is now higher quality than Ultra used to be, they've addd stuff. Running same FPS at Ultra should drive the GPU harder now. Running uncapped is very likely to run the GPU as hard as it can go.
Cap your frame rate. I find 24FPS (standard film frame rate!) is perfectly fine, or set it to 30; the difference between 30 and 60 is very small, anything higher than your refresh rate is useless.
Once you've capped frame rate (/console set maxfps 24, a lot easier than using the sliders), set your graphics down to High or even Good; tweak individual settings up or down. SSAO and Multisampling can both use a lot of processing.
Ironically, the best way to see which settings affect processing is to uncap your framerate (including turning off vsync) as you change them. Find the settings that give you the highest frame rate and still looks good, then cap your frame rate. That should result in the lowest processing load, hence less heat problems.
Remember, when you Apply on graphics settings, it will re-apply the frame rate cap (or no cap) that it saw when you entered System options, exit from that and go back in if you change it from the command line (/console maxfps 0 uncaps it).
09/07/2012 11:00 AMtemperatures hit 183F and then the fans will jump up to 4000 rpm and drop it down to 150-170F and then it cycles through those temps over and over.

Install smcFanControl and push the fans up to the point where temperatures and fan speed stabilize. smcFanControl just sets the minimum fan speed, the system will still push it up higher if needed. This way you can find an equilibrium speed that keeps temperatures low enough and stop the cycling.
Is there any info, or data I can provide to help in finding a fix for regular wow?
No, this particular problem is understood and the fix is in, we're just waiting for it to make it to the live client, and we're speculating that it will be this Tuesday.
