I made the upgrade to i7 6800k and after a few days I settled on 3.8 GHz with 1.265 v adaptive. (msi x99a raider). I have dual monitor and sometimes I use aida64 to monitor temps while playing, and today the cpu core voltage rose to 1.456 v and stayed there until I closed the game. My cooler is noctua d15 so the temp was bellow 55 C but still, is it safe?...

It's not just temps. Intel's cpus don't like high voltage(above 1.3). Any time spent above that is somewhat to very dangerous for the lifespan of the cpu.
That chip is on a mobo that fully supports overclocking. Included in that box of goodies is full control over voltage. Keep looking in the bios, you'll find the control for manual voltage.

Never use adaptive voltage! Take it off adaptive now. Set the voltage at 1.265v and do some serious stress testing. Keep lowering the voltage till it crashes, then add a little back till it passes the stress tests.

Adaptive voltage is known to cause the spikes in voltage you're seeing. I quit using it myself for the same reason. When OCing, it will increase along with whatever you add for additional vcore. In my case, when using adaptive I had mine set to 1.325v. Like you though, going through log files from both gaming and general use/web browsing I was seeing spikes of 1.425 - 1. 45v. Went back to manual voltage and never looked back.

It was a reading error. After 48 hours on the voltage got up to 1.748v which would burn the cpu instantly. I did reflashed the bios and it seems to be ok for now. But even so, the reading was off by alot

That's good, but I hope you'll take my advice and manually set your voltage. It's not hard, it will allow you run your chip cooler, or overclock it better, and it's a lot safer for your chip.

I only have adaptive or override. And 55 C isn't cool enough?
