High CPU Usage and Temps on Macbook

Hi Guys,
Don't know if anyone else has had this but:
I'm playing on a mid 2012 Macbook Pro 13" i7. Which used to run WoW without any issues at all. I DL'd this client fine but even the character creation screen is pushing my CPU usage upto >95%. My system temp then rockets upto 80c meaning I have to manually push the fan to 6000rpm. I've got no add ons and i've tried running everything on lowest possible graphic settings. My frame rate is perfect, just crazy high CPU and Temps.
Any thoughts/suggestions?
Cheers!
