Alphacool Eiswolf 2 AIO - 360mm + Reservoir

[AsHaH13]

Hai all I would like to add a Reservoir to my Alphacool Eiswolf 2 AIO - 360mm. How should I go about doing this and what are the items should I buy?
Would this also reduce the temps?

Thanks.

Is there a particular reason why you want to do this? You won't get better cooling performance. And should it be an reservoir with or without an additional pump?

Without. So no additional cooling? Ok just asking is there a thicker radiator or something like that?
