CPU radiator position

[Clipper]

Position of the radiator for the CPU, because as I am updating the PC, that doubt arose in me. My Corsair Series 500 case has three possibilities: front, side, and top.
By default, it only comes with fans in the front, so if I put the radiator (Corsair iCue, the typical 360 with built-in pump) in the front, I have a pull-push effect.
Ok
If I put it horizontally, I can't have a pull-push effect because the top cover is glass and the fans don't fit... And if they do fit, they'll be stuck to the glass (which I can fix)
My main doubt is:
We all know that pumps can move liquid to X height without any problem, so a pump from a kit probably isn't any marvel in terms of pressure... So I understand that the radiator in a horizontal position will make the pump work more relaxed, in exchange it will consume all the heat from the PC and the GPU will get fresh air.
Therefore, I think that the CPU temperature will go up and the GPU temperature will be lower.
If I mount the radiator in the front, in theory it will lower the CPU temperature and raise the GPU temperature and the pump will work harder.

Another option that I don't see clear would be to mount an R.L for the CPU on the GPU and put the radiator on the side, and fans in the upper free area, which in theory would be the panacea... Except for the pumps...
What do you think? Is it a crazy idea or is it unnecessary?

@clipper I'm not especially knowledgeable about LRs, but...

Considering it's only for the CPU, I would put the radiator in a horizontal position, the one where you say it will absorb all the heat from the PC but the GPU will get fresh air.

Why? Because if the GPU is air-cooled, you don't want to add extra heat to it. On the other hand, the CPU can receive a little more heat or, let's say, "cool a little less", it's more or less irrelevant, considering it has an LR just for itself. I mean, no matter how much extra heat the radiator receives, the CPU will still be the coolest element in the PC, because the LR always has a minimum efficiency (quite high).

As for adapting a CPU LR for the GPU, I'm not really seeing it either... So I would play it safe.

@Sylver
The thing about an R.L of CPU in the GPU is done with this:

It is just a simple aluminum profile with support for a few models of CPU R.L and a fan for the VRAM.
As I see it a bit cheesy, I could use the neighbors from the polygon and make some metal pieces cut with a laser and anchor the block directly to the PCB of the graphics card and machine a piece of delrim or methacrylate to hold the copper heatsinks for the VRAM.
And if necessary, put in a couple of low profile fans.
Which I don't think is too crazy

@clipper Man, if you're up for the adventure and have easy access to materials, go for it.
I thought the idea was to take the easy way out, but tinkering is always fun
