if i overclock a i7 8700k does the warranty void

If you break your CPU, and Intel can prove that it was your fault (i.e. if you increased the voltage past safe limits), then they have no obligation to replace it. K series chips are designed to be overclocked, but obviously within reason.

Officially, yes. If Intel can prove it if something goes wrong with your chip. Overclocking is not warrantied. It's deliberately pushing the CPU past the factory specs it was designed to run at. If you set the settings wrong, cook it or run the vcore up too high and damage the CPU, then that's user created error not a fault of the product. So long as you follow some guides, have a handle on what you're doing and do so with care, overclocking shouldn't kill your CPU.

 

So how does Intel can find out? Well, there is no recording device like a "black box" in an airplane or car that records the usage of them right up to a crash. But they can take it apart and see if any damage was done at the microscopic level. However it is unlikely that they'll do that though.
