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 :P
 
Without details of exactly what your system is it's almost impossible to give detailed advice.

Most 180mm and 200mm fans are almost worthless. 3x 140mm fans will generate more airflow.

If 480mm radiator is mounted as exhaust there will be very little heat in case so air will not get very warm. What case do you have? Assuming you replace the 2x 200mm with 3x 140mm with filters and block all openings in fan mounting panel not covered by fans they should push more air into case than 4x 120mm fans are moving out through radiator with no dust buildup .. and make sure you clean filters often. It doesn't take very long for them to collect enough dust to lower airflow. I clean my filters every couple of weeks, but our house is low dust.
 
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?
 
Whatever heat is removed from CPU & GPU is released into air. Same amount of heat into with either air coolers or radiators.

I wouldn't bother with a rear exhaust fan. I'm assuming the 200mm fans are the Megaflow fans with a 110cfm and 0.595mm H2O rating. While 110 isn't too bad the 0.595mm H2O is so low any grill and filter will limit the fan's airflow to very low levels, so with the 3x 120mm EK Vardar are rated 77cfm and 3.16mm H2O so they will pull more air out of case than the 2x 200mm fans can bring in.

what mobo are you running with your 2700x? with the GPU and the CPU I'd be running two rads top and front. inlet front, top exhaust and you can use the rear to blow air in to cool the VRM's.
 
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?
 
Given that you are cooling both gpu and cpu with water the only air flow you need is for the vrms. Putting a fan on the rear as an inlet will provide enough air flow for the heat sink. I’ve got two rads in my case with a ryzen 1700 although I’ve got a msi gaming m7
