Temperature registered at unplugged laptop (battery) @ 791 MHz only & free air:
Core: 55-59°C
Temp1: 76°C
So now it's switched back.
App: SpeedFan
Well anyway, I get these high temps because I heavily develop games in Visual Studio. It soups up avg 200 MB per project, ~300-400 at runtime. I also have a lot of apps running..etc..
