Input and Output for Alphacool NexXxoS XT45 Full Copper 480mm Radiator

[Ilovealphacool]

Dear AlphaCool,

I have purchased two Alphacool NexXxoS XT45 Full Copper 480mm Radiators, and would like to connect them in series.
So Output of radiator X ->input of radiator Y.
And then output of radiator Y -> to pump input.

I attach images below, and have named the different holes A - G.
The instruction manual was unfortunately not helpful, which I suppose is because the situation is "obvious"... but not for me

I really need to understand the internal layout or just to know what can be used as input and output so that before cutting any tubes, I have ensured that I have as short & efficient loop as possible (I am going to install everything in Corsair iCUE LINK 9000D).

From your shop-description, I think I understand that G is an additional hole to remove air from the radiators - but can it also function as an efficient output?

Thank you very much!

I’ll try to explain it in a very simple way—then everything should make sense.

The water flow inside the radiators is U-shaped.
The two chambers with the ports D, F, C, and E are each one chamber. For example, D and F belong to the same closed chamber. If water enters there, it flows on that side through the channels to the back of the radiator, where port G is located. There, the water is redirected once and then guided back to the chamber with ports C and E.

Port G is only intended to be used for draining the coolant or for filling. Otherwise, it’s not meant for any other purpose. If you were to route the water out from there to the next radiator, you would only be using half of the radiator’s cooling surface.

Was that understandable?
