2 loops @ 120mm or 1 loop @ 240mm

[GermanDrifter97]

Hello everyone,

 

I intend to cool a system containing a 3950X and a 2080 ti.

I want to watercool both, and because of space constrains I can only fit two 120mm radiators. I COULD however connect these two to virtually create a 240mm radiator.

Now I'm trying to figure out if the cooling would be better with one loop and both radiators cooling both components, or two loops, one for each component and with a 120mm rad each.

 

What do you think? A single 240mm rad would perform better when only the cpu or only the gpu is stressed, but when both work under full load, it might be worse? I don't have much know-how when it comes to custom watercooling.

 

Thanks a lot in advance!

both really need a 240mm to them selves. maybe put the GPU on water and keep the CPU on air or flip.

With the little space I have, the only option to keep the high performance hardware cool would be watercooling.

Thank you for your remarks, I will take that into consideration, although it was not exactly what I asked

or, you could switch to a slightly bigger case that can accommodate both. i think that will save you the effort.

they aren't going to be cool if you water cool them both without enough rad space.

my point was no reason to do it given they are going to suffer ether way.

Optimum Tech did two videos, one of which he uploaded very recently, where he tested a 120mm AIO on a RTX 2080 ti and on a 3950X. I might be wrong, but to my eyes, it does not look like the components are 'suffering' (GPU at 61°C, CPU at 68°C)

 

But you know what? Forget about the hardware, let's go back to basics:

Let's say I want to watercool both my CPU and GPU, whatever brand or model. I have two 120mm radiators on hand.

What installation would perform better?

• Having one loop with both CPU and GPU in it, and both radiators connected, resulting in a '240mm' radiator

or

• Having two seperate loops, one for the CPU and one for the GPU, with a 120mm radiator each

Together is a lot simpler and will allow one to stretch its legs more if they other doesn’t have much use. If both are under heavy they both will suffer the same as each having a 120

Ok thank you very much, that was all I wanted to know.

I’m trying to help you not have a bad time but do what you want.

Thank you for your help, I will listen to your tips

If you've got a tiny case then you should consider that 2 loops will also require 2 pumps and 2 reservoirs.

Or just 2 pumps at the very least.

It's better to keep the loops together.  That way the heat dispersion is shared.

 

However, you don't have enough radiators for what you want to do.   It is possible to change the Cpu to an air cooler and keep the GPU water-cooled.
