Heyo CheistiaN49
Nice to see you want to get into overclocking. I'm also an owner of the 4690k, and I'm currently running it at 4.2Ghz @ 1.1v. That is a small overclock and easy to obtain.
The basic idea of overclocking is to increase the core clock, and if it won't work correctly give it some more power. For example, I can run mine at 4.8Ghz @ 1.325v instead of my 4.2Ghz @ 1.1v.
It's basically a trial and error process. Not every processor overclocks alike, therefore you have to experiment on how far your CPU will go.
If you didn't know already, all of this has to be done in the BIOS, where you'll change the core clock and voltage.
Although, even though you might have found some sweet overcloking settings, you'll still have to look out for your temps. The Hyper 212 is good, but not amazing for overclocking, so don't expect mad overclocks with it. Keep an eye on the temps with something like HWmonitor, while running a stress test, such as Prime95.
Even though I'm happy to be able to run at 4.8Ghz @1.35v, I'm not really happy with how the temps are looking. I'm running my 4690k with a Noctua NH-D14. This is a pretty beefy cooler, and the CPU is still reaching about 85 degrees celcius under full load. Therefore I've settled with 4.2Ghz since I can run it under full load at about 60 degrees.
My own thumb rule is to keep the temps under 75 degrees celcius while under 100% load. Although, if you're alright with letting it reach a bit higher temps, then it's fine. Just don't let it reach 85-90 degrees.
Good luck overclocking your CPU!
