Question about ASUS GeForce RTX 2070S ROG Strix O8G Gaming

Many thanks for the answer
I am aware of all that and whether you think water doesn't belong in a PC is up to you, but I understand this view.
It's not that I think I need it but simply because I want to do it that way.
So can someone help me?

Why? On the one hand, many people think that water does not belong in a PC, and on the other hand, it cools excellently with the 3 fans. The problem is rather that in most cases the fans installed are not sufficient to provide enough fresh air... The part heats up the whole PC... So my tip: Simply install more supply and exhaust fans and all problems are solved! :) glg
