I totally believe the new SB processor run cool during light use, in fact, some review shows that 11' MBP 13" runs cooler than 10' MBP 13" during light browsing or anything light on CPU.I believe my situation with these processes running and eating up CPU %, the 199 temp is with Turboboost cranking. I've been on the computer now for about 3-1/2 hours after killing those processes, and I have only hit 125 degrees once, and this is with me working in Excel for that whole time... After 3-1/2 hours, I still have 75% battery, and show 5 hours remaining (moving target) and in that 3 hours the MBA has been cool to the touch and has had NO fan noise.
However, I'll be using the laptop for audio works which at time can be running about 70~80% CPU constant due to real time processing plugins in DAW.
Of course the new SB will be much more efficient and I probably will be using about 50% instead of the 70~80% on the same setup. Decisions, decisions...
