High CPU Temps on water

[reaperman197]

Hello,

 

I have been having problems with my CPU temps, I am using a Fractal Design Kelvin S36 trying to cool my I7 6700K but even after replacing the thermal past 3 times and now using Thermal Grizzly Conductonaut I'm still getting unstable temps peeking at 80c. It also just jumps from idle about 25c to 60c the moment it comes under load. I have linked a image of the temp chart while stress testing the CPU.

 

Can someone please explain why this is happening and how to fix it.

Thank you.

Wait, did you put liquid metal between the pump and the IHS?

Thanks your reply, yer between the IHS and water block.

How high's your voltage? Also, could the TIM underneath the IHS have "broken"?

[reaperman197]

In the bios it is just set to auto, intel tuning utility is showing 1.32V - 1.36V when under load. As for the TIM under the IHS im not sure, the CPU hasn't been delidded so its possible.

Just buy a new cooler. Or if it's new, try getting a replacement while being under warranty.

Is that really the problem? I didn't think a bad cooler would cause the temps to fluctuate between 40c to 80c all the time under load like in the image. I thought if it was a bad cooler that it would have a constant high temp.
