Hello everyone i am new here and i was wondering if anyone would be kind enough to answer two questions for me and hopefully put my mind to rest 
Yesterday i bought:
i5-6600k
2x8GB kingston hyperx fury @ 2666
Asus z170 pro gaming
Gigabyte GTX 1070
Noctua nh-u14s
PSU i am still using my almost 5 year old Seasonic X-660 cause its just that awesome.
Now i am completely new to OCing but i have read a LOT of guides and kept myself well informed before i tried anything.
I was able to get stable OC @ 4.4Ghz by setting manually voltage to 1.255 (at 1.250 1 core would fail in prime 95).
The issue i had was that overclocking would turn off power saving features on cpu so it would always draw high voltage and stay at max clock frequency.
After trying various things i managed to fix it by setting vcore from manual to offset and set it at -0.005 value.
Everything is stable tested it in prime 95 for a few hours.
Now my questions are:
1. Highest temperature my CPU got in prime 95 is 70C and mobo had according to HWMonitor 68 under full load. Are those good temps?
2. Since i set vcore to offset -0.005 my CPU works at 800Mhz and voltage drops to around 0.800 when not in use but while watching it in cpu-z voltage and clock frequency would jump up and down as soon as i do simple things like opening browser or anything else so i was wondering will that voltage and frequency jumping all the time cause any issues? Never really tested if its like that too with default settings.
Thank you everyone!
EDIT: Bonus Question!
It seems that i can OC only by increasing turbo boost frequency is there a way to turn off turbo boost completely and just OC CPU without turbo boost and would that provide any benefit?
EDIT 2: I did some more testing and from my understanding offset mode is basically auto vcore with an offset value? I am currently using adaptive mode set at 1.255v to be used when running turbo (basically when CPU is under load) with an offset value of 0.001v. This seems to be better because with offset mode there is a chance vcore will go higher than needed and with adaptive mode i set it at value i found most stable by using manual and it will be only used when cpu is under load (turbo mode turns on).
