[SOLVED] How do I position my radiators?

[marin358]

PC components:
Gigabyte x470 ultra gaming
Ryzen 5 2600x (might upgrade next year to r7 3800x or r5 3600x)
RTX 2070 Super
16gb (2x8) Corsair Vengeance LPX (if I upgrade my cpu I'll also buy faster ram)

I want to do my first custom loop. My case of choice is Lian Li pc-011 dynamic since I want to cool both my cpu and gpu. I'm going with 2 360mm slim radiators from ekwb (ekwb says that the cooling capacity of one of those radiators is 419W and my heat output is 380W but I'll still go with 2 so I can overclock). Another reason why I want to use that case is that I want one radiator on the side so I can place 3 corsair ll 120 rgb fans on it as an exhaust because it really adds to the aesthetics.
(the other radiator would go on the top of the case as intake).

My big questions are:
Ekwb says that the temperature of the liquid will be around 28°C and if the hot air from the first radiator + the motherboard goes through the second radiator, will that make the second radiator useless?
Also what is the best way to connect my loop (2 rads, 1 cpu block, 1 gpu block, 1pump+reservoir combo)?
And as it says in the title, how do I position my radiators if my positions of choice aren't good enough?
DISCLAIMER: I'm not looking for optimal cooling! I just want both my cpu and my gpu to not go above 70°C when gaming!


Excuse my mediocre english and thanks in advance.

Your English is better than many native speakers.

Order doesn't matter in loop configuration. The second radiator will not be useless no matter where it goes. It will simply strip more energy out of the water, as long as ambient temperature is cooler anyway. Once everything settles out the average temperature of the water at any point will be within 1 or 2C.

The GPU won't go above 55C with a full cover block on it, unless you do scary things to it. CPU will probably still reach mid 70s once you overclock it. Just the difference in the area of the chips.

As for your plan, I think having the top radiator as exhaust makes more sense, but only if you add intake fans at the bottom as intake.

I can understand your desire to make the fans front and center, so having the top as exhaust with the fans pushing through the radiator will make them visible. Doing it as intake you would have the fan structure/label pointing down into the case.

Really with that much surface area, it won't matter all that much.

As long as you aren't making a radiator sandwich, then you should be perfectly fine. As long as you have good case airflow, you shouldn't have massive temperature increases from the radiator exhaust from one rad to another. It just doesn't happen that way.

Assuming you'll have one radiator in the front panel and another on the top, you should be perfectly fine.

I've watercooled for nearly 18 years and wrote the watercooling sticky on the forums here. Trust me, there is a lot of misinformation out there and most of it comes from people who have never watercooled before.

And I used his sticky when I first sat down to do serious water cooling!

That's great to hear. I know that it could likely use a bit of freshening up, but most of the principle content still applies. And I don't claim to know everything...but I have seen a whole lot of watercooling threads and builds.
