I7 6700K temp spikes

[eazy11]

I have an i7 6700k (not overclocked, turbo enabled) and I initially had everything on auto on bios but I've realized that the voltages were set too high (my mobo is ASUS Z170-A) so I've managed to get better voltage by setting it to adaptive mode (+0.001 offset and turbo vcore on auto). Now the CPU vcore is way better, I get somewhere between 1.15V to 1.23 (on turbo mode). Ran a lot of tests, everything is stable and fully working.

The issue that concerns me are temp spikes, I know there are a few threads on this, but it seems that the spikes are common on AUTO voltage settings which I just changed. The cpu temp goes for a split second from like 20 degrees to 45-50 degrees and then 20 again just by opening Chrome for example. CPU cooling is a Corsair H115i, I can assure you that I don't have any contact issues between the pump and the CPU, and temps are extremely fine (around 60 degrees max after 1 hour of intense testing).

So at such low voltages, is this a normal behaviour for skylake architecture? Or is my chip faulty? It's a really annoying situation because my case fans go revving like crazy for split seconds because of sudden CPU temp increase...

I really would not mess with the voltages. it probably just revs up it engines while opening up things to get them done faster

I am having similar issues with my 6700k as far as temp spikes are concerned and the fans would go crazy!
I don't think there is anything you can do about the spikes, but you can remedy the fan speeds with ASUS AI Suite 3.
In the FanX section, run the Q fan (I think it's called), it's some type of smart fan check. Then for each fan increase the delays, mine are set at 2.1 sec on the sliders. Since those temp spike last less than a second or two, the fan don't speed up as soon as the temp goes up.
