Air vs Water Incase temps

[Scoiexx]

Heyo,

Trying to figure this out but, I'm looking to buy the

EK-MLC PHOENIX AIO (with both CPU and GPU blocks.)

I'm wondering what incase temps would I be looking at coming from air to something like this? I currently have two 200mm fans in the front, but I'm thinking of going for 3x140mm but again unsure on whether I would need that much airflow with this AIO whilst overclocking the burning 2700x

Ah I see, well what I'm thinking is.

Cooler Master H500p Mesh case with stock front dual 200mm fans,

Have the EK 360 rad mounted on the top with x3 stock fans. (I hear EK-Vardar EVO fans are good)

and a single Noctua 140mm exhaust in the rear.

I could go for x3 140mm at the front but would I require that much more airflow with this type of setup whilst having gpu & cpu in the same loop?

Ah right, guess this mesh ain't doing much good as I thought.

Might as well look at some 140's being that these 200mm are so weak O.O

I've got the x470 MSI GAMING PRO MB.

Wouldn't having a 2nd rad as an intake cause less airflow and more incase heat?
