That cooler is not going to be sufficient for that CPU. People with MUCH better full size coolers have had thermal issues with the 8700k. A minimum 140w TDP cooler is recommended. Not strictly due to the CPU, but also because the Z370 boards have mostly all shown issues with VRM overheating. The 212 EVO is a low end budget cooler, meant for light overclocking or as a replacement for the stock cooler on medium-ish TDP processors.
Your CPU will probably produce up to 140w TDP under full load at stock settings.
If the cooler DOES manage to keep up, it's going to be running LOUD at full speed anytime you do anything demanding or for extended periods of time. You are much better off going with a higher end cooler. Trust me, I've practically written the book on that cooler. Well, maybe not book, but you know what I mean.

I thank you again for giving me wise feedback! I'll upgrade the cooler but could you link me a cooler from you're opinion that can do the job great? & is it JUST the cooler thats the issue or is there anything els wrong in the build that I should change?
Personally, due to my own experiences with them AND the cumulative experience of a handful of other systems builders I know, I'd probably avoid the MSI motherboards altogether. Too many failures requiring an RMA. They are good about replacing faulty boards, but the fact remains they seem to have a higher rate of faulty boards than ASUS, Gigabyte and ASRock.
And that means having to remove and reinstall a board a second time, which sucks. I'd rather not have to do that whether it got replaced for free or not. Certainly not every MSI board is going to have issues, but the numbers seem higher than other brands.
I think the Gigabyte Z370 HD3P, while not incredibly better, is at least, better, with slightly larger VRM heatsinks. VRM overheating seems to be emerging as a common problem on the Z370 chipset with the 8700k and it's 6/12 core count.
