Where to put rad?

[Simon771]

I will be getting my 360mm PE radiator from EKWB today. I already have 240mm slim rad from them also, and just wondering if you guys have any suggestion where to place them  

using Define S case, and I can put 360mm on top/front and 240mm on top/front.

What do you guys think it would look better? 360mm on top and 240mm in front? Other way around?

 

Also, would there be any performance difference if hot water would go first trought 240mm rad and then 360mm, or it would be better to go first trough 360mm and then trough 240mm rad? I guess there is no difference, but it doesn't hurt to ask

 

Pump/res combo will be screwed on front radiator with that horizontal mout thingy that EKWB is selling, just so you know where everything will be  

 

I plan to use it this way: from pump to rad ... to another rad ... to cpu ... to gpu ... to pump. Or would anyone have any other suggestions maybe?

Why not have it go from pump  to CPU to rad to GPU to another rad then back to the pump. That way your not going from a hot CPU to a hot GPU. Also I also have a Define S I would suggest putting the 360 on top then the 240 in front because the front slightly hinders airflow.

No difference whatsoever.

 

I am using a top mounted slim 420 and a front standard 280. I think that looks much better than the other way around. I'd assume it is the same for 120mm variants.

 

You can and should instead mount the pump/res combo on the wall of the case. See my build log for tons of pictures documenting the process of watercooling (starts on page 2)

part of me just doesn't like the idea of running from hot part to hot part and says get a 120/140mm rad to put in the back lol, then the other part says it doesn't really matter

When I was using single 240mm rad for both CPU and GPU, my GPU temps were around 55°C. So hot water that came from CPU to GPU, didn't realy bother on the GPU.

However, my CPU was overheating, but that was because 240mm slim rad is not enough for both components.

 

Going from pump to cpu to rad to gpu to rad to pump would look a bit weird if you ask me

Yea it would look awful. I run pump>gpu>gpu>cpu>rad>rad. Temperatures are not affected in any way.

Like I said I know it doesn't really matter, still my intuition wants to say it matters, my intuition doesn't even science though

Just go res>pump>closest component>closest component>etc>res. Avoid going criss cross with the tubing. Keep your loop as small/short as possible.

well in this case I will go with my primary plan. Pump and res are combo, so from them to one rad and to another rad and then to cpu --- gpu -- back to res.

That way I will use as less tubes as possible.
