Overclocking my 4670k

[Waterhobit]

So I recently finished building a new system (something I haven't done in years).  I also decided to play with overclocking this system since all of my hardware is quality stuff, and because I can.  I tried to do all of the research I could on how to overclock since it is actually my first time.  I have been able to achieve a stable overclock at 4.4 Ghz using 1.275 volts.  I wanted to get some opinions, since this call requires more experience than research, but is this probably pushing harder than I should for my system.  I know I didn't win the silicone lottery or anything, but should I reconsider overclocking this high?  My max temps under full load with Prime95 are at 55C.

I know my temps aren't bad, but is my voltage too high?

You are running liquid cooling, so you are fine with 4.4GHz. I think a 4.5GHz or even 4.6 is possible for a 4670K, given that you have a good Motherboard that doesn't restrict OCing, a PSU that should be sufficient for OCing (unless you are running CF/SLI) and an unlocked CPU.

You're good even with higher clocks.

You could try with 1.3 v and see how high you can clock it? Those temps are pretty good yes
