A little worried..

[days_without]

I built my first system ever, I started overclocking it. It's an i5 4670k with a corsair h100i cooling in, all inside a corsair 750D case. It's at 4.2 GHZ right now, I've stress tested it and it very much stable. My only concern is the voltage is showing really low. I've got it set to 1.056 in the bios CPU - Z is saying its only using 0.723 is this a problem having it over volted? also its only running at 25-27C Idle and 55c with a 100% stress. My ambient temp is ~19.5.

bios settings are the most accurate.

i wouldnt worry and temps look good

Any way to tell what I'll be able to get out of this cpu with the current temps and voltage? I want a "safe" overclock I don't wast to risk shortening the life of the chip. I was hoping to get around 4.5

temps look good as long as u dont go over the maximum rated voltage u should be fine.
