Ok, using Intel Burn Test v2.54, RealTemp 3.70, CPUID HWMonitor PRO,
I get stable results (according to Intel Burn Test) at 4.6GHz, 1.3V, 84°C, 133.9 GRops. Before, I didn't realize that the voltage also changes during the test.
During idle, I'm at 800MHz, 0.71V, 32°C.
Hard drives and graphics card temperatures are between 41°C and 46°C which (along with the CPU idle temp) sort of gives an indication of ambient temperature inside the case.
I guess the CPU-Z stress test wasn't very stressful in comparison, but I wonder what kind of real world apps will behave like Intel Burn Test?
