This is my first post here so I hope I'm in the right place. I need some help regarding my most recent PC build.
Previously my watercooling setup consisted of a single EK SE 420x28mm radiator in the top of my Phanteks Enthoo Luxe case with 3 ML140 Pro fans, an EK XRES 140 D5 Revo Pump/Res combo, EK Supremacy RGB CPU block, Phanteks Glacier GPU Block and soft tubing. I was cooling my 8700k (with conductonaut liquid metal between the IHS and die) at 4.8Ghz 1.232V load voltage and my Strix GTX1080Ti in it's out of the box OC mode. Here is a picture of the old system:
For my new build I moved over the core components into the Lian Li PC-011 Dynamic case, however I switched from my old ROG Maximus X Hero to a ROG Maximus X Code, extended the reservoir, used rigid tubing and this time I'm using 2 radiators; an EK XE 360x60mm in the top and an XSPC EX360 360x35mm in the back as an intake. Both radiators are fitted with ML120 Pro RGB fans. Here is a picture of the new system:
While I am very pleased with the build aesthetically, it seems for some reason my temperatures are HIGHER than before...
Previously, after applying liquid metal to the CPU, in AIDA64 FPU Stress Test after about 15mins the CPU temp would be leveled out at 41-42C with the cores in the low to mid 50s. In 3DMark Time Spy Stress Test the GPU would stay around 50C. Both tests on my old system were running the fans at 1500ish RPM and the water pump at full speed.
Now, in my new setup, in AIDA64 FPU Stress Test after 15mins the CPU temp is at 46C and still slowly rising. In 3DMark Time Spy Stress Test the GPU is hitting 55C and hovering around there. Both tests on the new system were running the fans at 1500-1600RPM and the water pump at full speed.
Here are the AIDA64 screenshots.
To me this makes absolutely no sense? I should have much better cooling performance now that I have far more total radiator surface area and thickness. The only other thing I changed was that I used Kryonaut thermal paste this time instead of Hydronaut, but Kryonaut is supposed to be better. I know I applied it properly as well.
There are still some little bubbles in the CPU block and sometimes I can hear what sounds like maybe little bubbles moving around in the top radiator (EK XE 360), but can those things really make that much of a difference?
I really need some help figuring this out. I am so happy with how the build turned out aesthetically but it's really bringing me down that all that work is leading to higher temps..
