Great improvement on the beta.
MBP Mid '10, same conditions that would give me 90ºC+ on live (FPS capped at 28, low to fair settings - as in, low shading details, low particle density, low water, sunshafts disabled, the new setting that I forgot the name disabled, and everything else on fair), won't get me over 70º something degrees.
If I go up to 33 FPS, I can go to 82-4ºC in heavy AoE condition on Org dummies. Won't go past 80ºC on the outside Pandaria world (maybe on the beginning, everybody questing together, sep 25th).
I only get to 89ºC if I go to 38 FPS (which would be the almost the same as not capping my FPS, except I don't have sudden FPS spikes when I cap) in Org - same conditions, heavy AoE dummies. Don't go past 80ºC in Pandaria as well, open world (even when my frame rate goes lower than 38 by itself, meaning, 38 is almost too high for my machine - it always has been, even on Cata, only difference is that I could go fair to good settings, but I guess that's the price to pay for having an outdated computer).
TL;DR: Even though my CPU goes higher than 100% (two cores, what can I say? - it's always been over 100% on Cata anyway), this new build is obviously WAY lighter be it on the CPU, the GPU or both. Coding stuff I don't understand. Thing is, it worked.
Edit: Also, I run the beta from my external FW HD. I don't know why, but running WoW from the external HD always made my computer hotter, so, chances are these temperatures can drop 1-3 more degrees, when this patch is deployed and installed on my "normal" WoW.
