I'm using Premiere Pro cc 2015 on a Mac book pro i7, 16gb ram and ssd drive.. When I start Premiere and i open a project (on external thunderbolt hdd with all media) i can work for 3 minutes and than the fan of Mac go to 6000rpm and the temperature of CPU is around 104 c..
The same thing happen with After Effects but not with Prelude on the same media.
This happen with cuda acceleration, with Open GL and also with mercury playback.
I realy don't know why.. The CPU work around 20% but the fan and the temperature is realy high..
