Law-II: The Intel temperature spec you are quoting is called the tcase temperature. It can only be accurately measured by cutting a groove into the top of the CPU heatspreader with a Dremel or similar tool and then you need to run a thermocouple to the geometric center of the IHS and apply some solder to hold it in place. This specification is intended for system builders that are designing computers for the mass market. Intel does not expect individual users to purchase sophisticated equipment and hack up their new CPU just to make sure it is not getting too hot.
The whole purpose of that tcase spec is to make sure that during normal use the CPU will not reach the thermal throttling temperature. This insures that the CPU will be able to operate at its rated speed. What controls thermal throttling and thermal shutdown? Intel uses the core temperature data to control this and that is the number that RealTemp reports.
The RealTemp - Thermal Status area reports if the CPU is operating within the Intel spec or if the CPU is being forced to slow down due to thermal throttling. If RealTemp says OK, your CPU is OK and is within spec.
Even at 100C this CPU is still operating at its full Intel designed CPU and GPU speed. If this was hurting the CPU or GPU then I am sure that Intel would lower the thermal throttling temperature to prevent this from happening. They actually bumped the thermal throttling temperature up to 105C when they went from their 2nd Generation Sandy Bridge to their 3rd Generation Ivy Bridge CPUs so in my opinion, that shows a lot of confidence in their CPU's ability to operate 100% reliably at some very high temperatures.
If a CPU ever does get too hot, it will automatically slow down to protect against it being damaged. If something crazy happens like the CPU heatsink falls off, the CPU might reach the thermal shutdown temperature which means your computer will turn itself off. The thermal management technology that Intel uses is second to none. There is no reason to worry about your CPU's core temperature. Intel CPUs are smart enough to look after themselves.
