Depends on you

Works fine for me, if I'm just doing low performance stuff like browsing or watching a movie or whatever, it'll hang around idle voltages, and raise the voltage to 1,3V max when doing performance intensive stuff like gaming or benchmarking.
Do you mean the lowest *positive* offset voltage? I can set it to +0.005v, but technically it goes negative, and it goes way lower than 0. So the lowest possible offset voltage would be unstable at idle. That's where i'm confused. I have been trying to see how far negative I could push the offset voltage and get it stable at boot/idle. I figured from there, I could just up the turbo boost voltage until it's also stable during stress tests.
Also, I can't turn my turbo voltage "off" unless setting it to "Auto" is essentially the off switch. Otherwise is starts at +0.004v and goes up from there.
Yes, I mean the lowest positive offset voltage (+0,005V). If you really want, I can look in my bios later to see what settings I exactly use, but it should be like this:
When you use offset voltage, it theoretically should run at like ~1,1V + your offset voltage value. That's where it runs when it doesn't do anything/only light tasks (only in theory, actual it goes a lot lower in voltage if it idles, IIRC around ~0,9V).
Now if you set additional turbo voltage, this is how your voltage should behave when you put it under load: "normal" voltage (~1,1V) + offset voltage value + additional turbo voltage. So for example for me it should be something like this: 1,1V+0,005V+0,15V=~1,25V.
So it would have around ~0,9V when in idle, and depending on what tasks you do it can up the voltage up to a max of 1,25V (using my example).
Hope that helps.
I currently run a i5-3570K @ 4.7GHz / 1.256V with a Noctua NH-D15 and 5x Noctua NF-A14 FLX (140mm) fans.
I had a Hyper 212 like you before I switched to the NH-D15 though, and 4,5GHz was no problem, so you should be good.
