I7-6700K Core Temp issue

[Heewon]

I am  testing on Prime-95 using CPU-Z, core temp and real temp. Everything is indicating that 3 of my cores are rolling around 60-65 degrees average but my other one is rolling around 35-45 degrees with peak at 50. 

 

I have an Asus ROG maximus VIII Hero mobo and I7-6700K. Currently overclocking at 4500MHZ. I have a Corsair H110i GT Cooler in a Corsair 760T case. Had a few crashes right when I started running prime95 until I raised the core voltage to 1.28 V. Core temp is indicating that the hotter 3 cores are taking 100% load but the other one is taking between 0 - about 40% load. I was wondering how I should fix this? I am planning on overclocking to 4.8GHZ and keeping a solid temp within 65-70 degrees, but I don't think that will be possible without the last core taking on some of the heat. 

 

P.S. This is my first pre-built computer and first time Overclocking.

Thanks in advance. I love this community.

It depends on the tests being run. If the test doesn't use all the cores then you'll notice lower temps on one of the cores. It seems perfectly normal to me though.

Figured it out. Core voltage was too low. is 1.408 V safe?

Seems high.

I put it to auto for 4.5 and that's what it went to. I agree that I feel that it is high for the clock speed
