high temp on corsair h115i and i7 6800k

Hello, I bought a corsair h115i to liquid cool my intel i7 6800k with the goal of having a silent build. 
the fact is that my cpu is reaching more than 60c on idle, and the h115i temperature can't stay cool.
I'm writing now, after around 10 minutes of computer activity, with just one web browser opened and few apps in background (steam, epic games, avira, mail) and my cpu is around 80c, and my h115i around 57c.

I don't know which are the "normal" values for h115i but I read people with temperatures > 20 < 40c with computer running intensive tasks.
If i run intensive tasks all my cpu cores go to 100c (without any throttling or strange behaviours to be honest).

I don't know what to do really, I changed the thermal paste 3 times with very little enhancements on temperatures. 
I live with the fans going almost full speed all the times, it looks like i'm leaving in an airplanes hangar.
If I put my hand on the radiator of the h115i it is very fresh, if i touch 1 tube is very hot, and the other tube is quite cold. If i touch them i can feel water moving inside so i think the pump is working properly.

What should i do? thanks


Here's some screenshots:

Correct and you are well outside of that zone. When the coolant continually escalates from the moment you power on, then the heat is not getting to the radiator for dissipation. Most of the time this means there is a blockage of some type and this is how life ends for a “no maintenance” cooling system. If you are still in the 5 year warranty period, contact Corsair for a replacement. In the meantime you are going to have difficulty. The coolant temp is the lowest possible cpu temp, so that puts you at 60-70C on the desktop doing nothing. If you load further, you won’t be able to bring the temp down even when you stop. 
 

 

There is no permanent fix and immediate remedies are few. You can try tilting the case so the inlet/outlet hoses are above the block, tapping the pump/block, or in a worst case scenario removing the unit and shaking the cpu end to try and unstick the blockage. However, even if you succeed this will be temporary. There is no place for the debris to go except right back to the choke point in the cooling fins. You need to move toward a replacement.

No, it can’t be on the cpu side. If the coolant is moving, you can’t heat it up to 40C over ambient even with no fan speed. This is classic “reduced flow rate” behavior. If you set the pump to max you might be able to get some use out of it, but this is a terminal condition and how most AIOs meet their end.

I'm writing this last post to tell you that you were right. Even tho the cooler was looking like it was working fine, it was not. I changed it and finally my cpu temps are not going past 30c. 
I'm so happy.

Thanks a lot.
