My i9 12900k CPU and 4090 GPU, cooled by an industrial automotive pump with a water chiller, pc temps before with d5 pump 70-90°C (CPU) and 70-80°C (GPU) in CS2 and GTA. After cleaning the water blocks, upgraded to new pump temps dropped to 45-55°C. With the chiller on, they went down to 27-37°C, with the water chilled to 15°C. Room temp is 24-26°C with AC. I'm using glycol-free coolant with benzotriazole, BAC, sodium molybdate, and sodium tetraborate inhibitors.
