Hi! I tried to overclock my i5 on gigabyte GA-z170-d3h board, I have 1.260-1.275v when idle and something like 1.220 on 100% load in occt or cinebench r15. Frequency drops in idle to 800's Mhz but voltage is still higher than in full load (all cores 4400 Mhz). I have power savings options set to auto, c6/c7 to enable. Overclocked by changing multiplier to 4.4. Voltage set in vcore section. I don't want to harm my CPU lifespan, so i really want it to not work on that high voltage all the time. Thanks for reading and helping!
(4.4Ghz 1.285V) i5 6600k Drops core frequency in idle but doesn't drop down high voltage

If you put the core voltage in manual mode, the motherboard sets the VRM to ignore the CPU state and operate at constant voltage. The "lower" voltage under load is simply due to voltage drop when under load between the VRM and wherever the monitoring chip reads the voltage from.
If you want core voltage to follow load, you need to use "offset" voltage tweaking but this may lead to lower stable overclocks.

But when it is not an offset OC why it drops down frequencies? in manual cpu should also run always in 4.4 AFAIK.
Also, how to do this offset oc on gigabyte board? Could you help me? In voltage section i have only 2 options related to CPU voltage, but second one is now in unavailable, dark grey colour- This option is called Automatic Vcore and is set to auto.

Offset OC? What is that?
When you change the multiplier, you are changing the MAXIMUM multiplier. If SpeedBoost is still enabled, the core clock will still get dropped down when under light load.
If you want to tweak the core voltage yourself, you need to put it out of automatic first.

So, if I want my cpu to down-volt I have to return to the stock settings, than use Automatic Vcore (DVID) to add voltage?
But is it that big deal? Is my current 1.285 safe for my CPU for everyday use? Can I stay where I am without worrying about my computer life?

You are running the chip out of specs, nobody knows what will happen and how soon.
If Intel was 100% confident that they could produce a marketable yield of 4.4GHz CPUs guaranteed to last for the whole warranty period under worst-case operating conditions, they would likely be shipping locked CPUs running at up to 4.4GHz stock.
