Hello, i just bought new PC and i started OC. (BTW sorry for my english, im still learning)
Im using Gigabyte z97x-gaming 3 and be quiet! pure rock cooler. And i dont know if i did everything alright.
4.7Ghz, core voltage set: 1.2v
max temps in prime95 26.6 are 75oC
no bsod or anything like this

If it doesn't bsod in games or prime95 after 24 hours then it sounds like you just won the silicon lottery, nothing to worry about and it's perfectly possible with a high quality chip. You could use cpu-z just to make sure it's actually hitting 4.7ghz though. I've run into cases where no matter how high I crank the multiplier the intel boost just decides not to go any higher than some set number.

I get 4.5GHz at 1.32V on my 4670k but I have one core at ~83-85C and another at ~72C under load -_-. Maybe i should delid it soon, haswell's TIM is atrocious.

Sounds good :) One more question, right now im using igpu from i5 because my gpu is still on the way. I oc'ed igpu to 1600mhz and set 1.1v. In tests like prime95 or OCCT will this get my temps higher than w/o igpu on?

In most games the i5 will be faster, the i7 might be faster in cities skylines and ashes of the singularity but that's about it. For video encoding and processes that use all 8 threads, the i7 will be faster no matter how much you overclock the i5.

Skylake has an average of 10% better performance per clock, so in tasks that are single-threaded, a 4ghz Skylake CPU will often perform similar to a 4.4ghz Haswell CPU. It'll do so drawing far less power, of course, and it has hyperthreading so anything that can fill all of those threads will perform something like a ~5.7ghz Haswell i5.

These are very rough approximations. YMMV.
