We always recommend to use the PC at the stock configurations, to avoid any kind of damage.
The overclocking is actually not supported, the customer has the option to do that, but it will be at his own risk.
Remember also, that the overclocking is not cover under warranty, in case something happens to the processor in order to replace it, the tuning protection plan is needed:
Based on the previous information, if you use the processor at stock configurations, it can reach 64°C inside the case, and that is expected.
When the PC starts to overheating it will get freeze at first, it will start to throttle, and then if it reaches 90 or 95 it will go off by itself.
Since Intel does not test the processor outside the stock configurations, we cannot guarantee that it will work properly, or if those temperatures are correct, because at some point could get really hot and that is the thing about overclocking the processor, that could get damage all of a sudden.
Altering PC clock or memory frequency and/or voltage may reduce system stability and use life of the system, memory and processor; cause the processor and other system components to fail; cause reductions in system performance; cause additional heat or other damage; and affect system data integrity.
Intel assumes no responsibility that the memory, included if used with altered clock frequencies and/or voltages, will be fit for any particular purpose. Check with memory manufacturer for warranty and additional details
