Hi again. I tried some things. First changing the upper fan from exhaust to intake changed nothing so i left it as an exhaust. I read somewhere that i have to run Prime95 without AVX enabled. Disabling this gave me 4-5C less. Taking out the front panel temps decreased 3-4C more. So finally i managed to have to the cores from 77-84C and 85C at the package. At the end i brought down to 1.250 the vCore but did not change anything. I see the system stable till now so i will leave it there. Last thing i noticed that the water temp came down to 32,5C. How do you see this?

Thanks both for the help. I will check as soon as i will be back home because i am out now. What i was thinking is that maybe it is quite hot the case inside. Before the installation of the new Mb cpu and the h115i with that case at the front i had no fans. I had only the 2 exhaust fans back and up 120mm both and my temps with an OC i5 6700K to 4.9 and an average fan cooler were ok. Now which I installed in the front the big fans of the h115i and intakes the room air through the hot radiator, I suppose that the air which comes into the case it is kind of warm correct? Are those two exhausts enough to take out this air? What if i change the exhaust fans with better ones in terms of cfm?At the top i can put a 140mm in back no. Do you believe that can make a difference? Both of the exhaust fans now are connected to the PSU so they work 100% all the time.

I have an NZXT S340 case. The radiator for that case you can put it only at the front in push mode and intakes air. The 2 case fans back and top are exhausting. I have a GTX 1070 too in case it matters! I was thinking to try change the original thermal paste. What do you believe? Is it worth the time? Because i read that most of the people they didn’ t see big difference.

The 38C are after the load. I start with 29C about.It should be ok since in the room i have 23-24C. The thing i think how much do i expect to raise with full load.Because if the 38,5C are not hot enough when i run Prime95 means maybe that i have not a good contact between cooler and cpu right? So first when i have the cooler working to extreme using Prime95 what should i expect as a water temp?

Hi again and thanks for the reply. I am not sure that i understand the question but in Bios i set up the cpu voltage to 1,285V. Coolant temp is 38,5C. According Prime95 vCores 1,223. I run the test again and now my avg temps are Core 0 at 95, 1 at 91C, 2 98C,3 95C, 4 97C, 5 92C. All of those after about 40 mins running Prime95.

Hi. I am new with water cooling. I changed i MB and my CPU to GB Z390 Aorus Ultra and i7 8700K OC to 4,8 GHz. I installed a new H115i Pro for the cooling but i think that my temps are quite high and unstable. To idle HWMonitor detects CPU Cores at around 37-40C degrees mainly with Package to be even more 5-10C. My temps are not stable i believe changing all the times between 37-50C and when i use any game my temps goes 80-85C. With Prime95 100-105C. I have spikes even to 73C. I set up fans and pump through iCUE to balanced mode but even at extreme it does not change a lot the things. Checking the dashboard of iCUE i see the pump rpm not to be linear but having repetative spikes. Is this normal? I reseat the cooler, tight the screws more, untight the screws but temps are not changing a lot. Any help will be appreciated. Thanks
