My original testing was on a Core 2 Duo. The idle calibration factors were also designed around the Core 2 CPU's sensors so there is no need to use them on your Core i CPU. The first generation Core i CPUs are ovens, especially when overclocking. You have also disabled the low power C States like C3 and C6 so that will create extra heat in the cores. As long as your CPU is stable then there is no need to worry about its core temperature. Your core temps are fine. Glad you are back to running at full speed.
