Just used cinebench, tested both multicores and single cores. No resets during the run, CPU Multicore 9872pts, single core 1320pts, MP ratio 7.48xFurMark just hits the GPU it doesn't do anything with the CPU. That's why I suggested using cinebench looping to single out the CPU. OCCT also has very good CPU testing.
If anything shows up at all it would generally be under system as software isn't going to shut off your computer.
