Technical notes:
Overclocking is not the best solution in terms of circuitry - you output nodes beyond the boundaries of the stability of their regimes of time, increasing their heat and thus speed up the degradation of the physical structures of semiconductors - two.
And considering that Intel CPU since Iwy Bridge used possessing far better thermal properties "thermal grease"
local overheating and metallurgical sample crystal when operating in conditions prohibitive for them guaranteed. Intel as a producer interested in increasing sales of their products, and if people use it in the emergency mode, it God himself ordered to release a version of the chip that is they do allow and burn after working a little longer warranty period that you have purchased a new product, but it could show it claims for what the old burned down. Such things are laid in the Terms of Reference for the development, but the consumer does not speak about it.
