New Cooling Installed, But... (Patreon)

Is there someone who know how to setup liquid cooling and CPU correctly? Not mechanical because its already installed physical and its done well. But I mean via software or bios. I just feel that I've did everything wrong. Voltage and timing are jumping from low to high and I can't hold stable temperatures. Even when CPU is not used a lot on idle or DAZ3D that doesn't use CPU for rendering. Still testing it trying to find a solution.
