    it makes no difference, the water will be the same temp throughout the entire loop +/- 1 or 2 degrees
    the water does not stay in one spot long enough to be "heated" in one block before it goes into the next
    i run water from 2 x 290x's into the cpu, max temps ~50 while gaming, 3 x 360's, d5 on 3 iirc

    Do you require this radiator setup to cool the water if the temp only changes by 1 or 2 degrees within the loop? Or is it 1/2 degree per block?

    yeah thats about the same for me with 2x280s..
    cpu can get a little hotter ( 2700X ) but thats due AMDs aggressive power peaks.

    If tuned to 1.225v , it never hits 50 @ 4.1G w/ 1080Ti @ 150c/200m OC...
    thats melbourne ambient..

    If you are not planning to oc your 9900k, 2 360 rads would be ideal for 9900k + 2080, for soft tubing the order of GPU and CPU blocks have no impact in performance, flow rate is 300-400L per minute, so fluild will cycle something like 5 times a second, thus no temperature difference in fluid. Adding more rads and help temp under load for long period of time and reduced fan noise, but effect is not significant, add another 360 probly can redice fluid temp by under 5°c.
