[SOLVED] Bigger AIO for gpu or cpu?

[WolfgangIII]

Specs:
CPU: 9900k -> NZXT kraken x52
GPU: GTX 1080 -> NZXT kraken g12 with old corsair 120mm rad
Mobo: Asus z390a prime
Ram: g skill trident z neo 3400mhz
Case: NZXT H500i

I was looking to replace my graphics card's aio with a new one since it has been on my pc for a couple years. I originally bought the aio from Facebook so I don't know how much life is left in it. If I were to replace it I was wondering what cooler to use for my cpu and graphics card. I plan on having a very light overclock on my cpu and something a little more intense on the gpu. The cpu overlook for the cpu will just be a automated one from the motherboard, the gpu is a comfortable overlook that I copied from somebody else's 1080. Also, my 1080 is water cooled because I was gifted a founders edition and the Temps that it ran it made me worried even though I read it was normal.

My main question would be that when I replace the 120 mm rad should I put the 120mm on the cpu and the 240mm on the gpu or just keep the orientation the same as is it currently.

Thanks

Edit: Also, another note to add is that I was watching gamer nexus's video on cooler orientation. It made me think that the 120mm on the back of the case would run best on the cpu and the 240 on the front would go best connected to the gpu(in reference to water flow in the line).

I'm not familiar with the Kraken series so forgive the obvious questions.

Will the waterblock mount from the CPU mount to the GPU? If not then your question is moot.

If so then switch the 240mm over to the GPU and replace the CPU cooler with a quality air cooler which are comparable to 120mm AIO setups.

As for water flow in lines, from a practical standpoint, you just want the lines going to the radiator to sit higher than the system's pump. In the H500i, both radiators would sit higher than the CPU/GPU pump as long as the lines going to the radiator are placed on top. This is assuming that the system has minimal air pockets which is hard to check with AIOs and assumed to grow as AIOs age.
