PC water cooling single or double loop or maybe some changes?

Hello, at the moment I have 3 heat sinks 360, 240 and 120mm for CPU and GPU and I'm thinking about small changes because the GPU greatly increases the CPU temperature. When I test the processor itself, the maximum temperature is 56-58 * C but when I start the CPU and GPU test, the processor temperature increases to 85 * C and in games about 60-70 * C. The processor is 9900K at 5GHz and GPU RTX 2080 Super. My loop:  pump > 360 radiator > CPU > 240 radiator > 120 radiator > GPU > reservoir . I am thinking about changing to a pump > 360 > CPU > GPU > 240 > 120 > reservoir in this configuration the card will be right behind the processor and there will be 3 radiators before of the processor or I thought about buying such a pump and doing it separately for GPU and CPU with this pump for GPU https://www.overclockers.co.uk/magicool-dcp450-12v-dc-small-form-factor-pump-and-reservoir-wc-025-ma.html. The graphics card temperature does not exceed 45 * C and when I start the game stream, the CPU temperature reaches 75-80 * C.
