snowfun87: Thank you very much for joining the Intel® Processors communities. We will do our best in order to provide the information you are looking for.
Remember that altering clock frequency or voltage may damage or reduce the useful life of the processor and other system components, and may reduce system stability and performance. Product warranties may not apply if the processor is operated beyond its specifications. That is the reason why there is no documentation available about overclocking, which is the safest voltage value, or the limit that the processor can reach, let me apologize for that. However, on the link below you will see a range of voltage that we recommend to set for this processor, any value within that range will be safe for the processor, page 24:
In regard to the temperature of the processor, on the link below you will find the T-case temperature which is 67.9°C:
Any temperature above that value will be considered as overheating, but that is under stock configurations and BIOS settings to defaults. When you do overclocking it is expected for the temperature to increase.
I also encourage all the peers viewing this forum that if they have more suggestions or comments on this matter to post all the details on this thread.
On the following links you will find forums for overclockers, in there you might find additional information on this subject:
