i5 6600k weird temps under load

Hello all,
I finished my new pc a couple of days ago. I am new to overclocking, but after some testing i ended up at 4.6Ghz with a vcore of 1.295.

For stress/stability testing i used AIDA64 and i stressed the FBU.

AIDA64 testing
Ambient temp: 18-20C
Idle load temps 25-27C on all cores
Full load temps 55-60C on all cores


I did this test for a couple of hours, but later i wanted to do a stress test with a different software, so i installed Prime95. While stress testing through the "blend" option the temperatures was somewhat familiar to the ones achieved through AIDA64. But when i started the small FFT test in Prime95, the temperatures jumped a little on core 2,3 and 4, and a lot on core 1.

I took a picture of RealTemp, and the cores looked like this:
Core1: 81C (Fluctuated between 76-82C)
Core2: 67C (Fluctuated between 65-68C)
Core3: 71C (Fluctuated between 67-72C)
Core4: 65C (Fluctuated between 65-68C)


My question is if this i normal? Could not find any threads with the same problem, as the temperatures are "normal"/Close to eachother when using AIDA64.

Any help would be greatly appreachiated!

Cheers
Jonas

Are you using "Manual" voltage setting in BIOS to lock it at 1.285, or do you use Adaptive or Offset?

And do you have any updates? Any success? I had similar issues documented in this forum thread below, and dropping to 4.4 on Auto voltage has really improved things, but I'd like to tweak a bit more to get my DDR back up to 3000MHz and get back up to at least 4.6 under 1.3 volts, if possible.

If the temps are not similar across all cores, then it seems that the overclock has failed. It also seems that your voltage is a bit high. Try looking into 4.6 Ghz at 1.29 or even 1.285 volts. If that doesn't work and you want lower temperatures, 4.4 or 4.5 at 1.27 should work.

Thanks for the answers.
I now changed the voltage to 1.290 and later 1.285, and the temp on core 1 increased further to around 85 degrees during the Prime95 FFT test... Could it be the thermal paste not being applied the right amount where core nr 1 is located?
I also noticed something else now. When starting the blend test, core nr 1 is not working...(Worker nr 1 has stopped working, and it displays 1 error)

I changed the OC to 4.5 at 1.27 and the same problem exists.
