Everyone's been saying that Ivy Bridge/Kepler should be running cooler -- however, my temps are stuck at 65C just idling with a display plugged in (on discrete GPU). If I go integrated GPU, I get around 55-60C idling. My 2010 MBP idled around 50C. Even with the fans maxed at 6200 using smcFanControl, using an external display and CPU under 5% utilization, my temps are 57C. Perhaps these Ivy Bridge MBPs have an overdosing of thermal paste? I'm a bit hesitant to dig it apart to find out, even though I have a fair amount of experience building and tinkering with desktops.
