Need some advice about cooling my 5800X3D and 3090

So this is my current situation/setup.

CPU: 5800X3D cooled by a Alphacool Core 1 CPU-block connected to a alphacool eisbaer extreme 280 radiator/resarvoair/pump-combo.

My GPU is a ASUS ROG STRIX 3090. The one of the fans have started to give out so it's time to do something.

But what to do?

Here are the options:

I have the EK Stix vector GPU-block and backplate.

I also have a 320 alphacool radiator and two 240 ones with slightly different height?

I also have the cables/adapters needed to deshroud the GPU and put two 120mm noctua industrial 3000 RPM fans on it.

Now if I go down the watercooling route I have a few questions.

Form my research I think the pump in the eisbaer will be enough to run both the cpu and gpu and possibly two radiators?

I am thinking about getting a 280 radiator for the front simply because 140 mm fans will be quieter.

I also have a bunch of artic P.max 140 fans and they are very good imo so was thinking about going with those.

Also a quick thought would the one radiator I have be enough for both cpu and gpu or is that just asking for problems?

I mean the GPU can pump out 450 watts on its own.

Thank you for any tips and recommendations :-)
