Lowering 6700k vcore

So let me set up the scenario...

Ever since I upgraded to 6700k and z170 pro gaming I've had freezes during graphic-heavy games like Witcher 3 and Deus Ex MD. I get a loud static noise from my headset and everything just freezes in place including my screen (no blackscreens or the like).
I've had 2 different GPU's (GTX 980ti and GTX 1080) during this period so I'm pretty sure those aren't at fault.

So what I've come to as a conclusion is that my CPU might be the bandit of the bunch.
According to HWMonitor my CPU temp gets above 72C (at the very least) at times during named games even though I'm sporting a Hyper 212 EVO.
So with the help of google I've found threads on this site that discuss that 6700k uses a too high vcore on standard settings. After reading such threads I checked HWMonitor which showed my vcore and VID going well over 1.3v. When I saw this I wanted to lower my vcore to about 1.240v for starters but this is where I stumble.
No matter how many times I've tried these past days I can't seem to get the vcore to change, even a little.
I put AI Tweak "thingy" on XMP, set all CPU cores to sync at 40x, switches CPU core/cashe voltage from auto to manual with a value of 1.240 and lastly saves and exits.
When checking my core voltage value on bios again it hasn't changed from 1.296v and HWMonitors values doesn't change either.

So my question is: What am I doing wrong? Please help!

BIOS version: 1206.
Win 10 64bit.

Don't use manual vcore, it prevents voltage from dropping during idle and partial load, resulting in your CPU running at too high a voltage during most of the time you're using it. I have my chip undervolting with a negative offset.

However, 72c is nowhere near going to cause problems with your CPU. It will not throttle from temperature until 100c, so likely temperature and voltage have nothing to do with what you're seeing. I would suggest you open up resource monitor or task manager and keep an eye on your disk and I/O utilization. Whatever is hitting 100% when this is happening is your culprit.
