Safe CPU core voltage

So I am using a gigabyte z270x ultra gaming motherboard and a intel i7 6700k. I am getting 32-33 idle temps for my CPU. I have seen other people getting way less idle temps and I am running a corsair h100i liquid cooler. Upon loading to the bios and going to the CPU core voltage setting the vcore is set to Auto:1.275. I want to tone it down a bit but don't the the safe spot. Any recommendations would greatly be appreciated.

all CPUs are different in their performance against voltage

it's just overclocking but you do the opposite with the voltage

set it to manual and lower it by 0.01v. Then run a stress test and see if it passes

Then repeat the process and keep lowering the voltage by 0.01v each time until you find the lowest you can go while also keeping everything stable after a complete stress test

Idle temps depend a lot on your case air flow and the ambient temperature in your room...
To put that into perspective, it's summer here in Greece so we're at 30ish C and now my 7700k has 29-31 idle temp, with a corsair H105... so 32-33 isn't much if the environment is warm :)
In the winter, my idle temps were about 24-25 C.
Dropping vcore does very little for idle temps as it should drop to 0.8 (or thereabouts) when idle, if you have windows balanced power settings and haven't messed around with power saving settings in the bios.
