I received my RMA'd IPC2. Unfortunately, this IPC2 exhibits the same thermal overheating as the previous unit. Though over a slightly longer time.
I've attached graphs of the CPU temps when running LinPack via OCCT. The graphs are from a completely cold start. First boot after machine turned off and everything at room temperature.
Note that I set OCCT to stop the tests when the cores go above 90C. The temperature does continue to increase to 100C whereupon CPU throttling kicks in. I just didn't see the point in repeatedly hammering the CPU.Subsequent runs heat much faster: five minutes or so to thermal maximum. Running Prime95 on all cores heats even faster than OCCT, but it doesn't make the nice graphs.
I'm running a fresh install of Windows 8 and no BIOS modifications from the default except to display the POST screen for 3 seconds before continuing. I've installed 16GB memory and a SSD.
Here are links to the three pieces of software I'm using for testing.

http://www.alcpu.com/CoreTemp/Q1. Am I seeing expected behavior for IPC2s?
Q2. Is the I7 IPC2 designed to be run full out (both physical and both logical cores) for longer times?
Q3. Any chance you could run either OCCT or Prime95 on a sample there and see where the temperature maxes out for a known good sample?
