Aurora R7, 2080 Ti, fan problems

Hi. I got an Aurora R7 with i7-8700k water cooled and RTX 2080 Ti. Like everyone else, I got fans problems causing them to spike at vacuum cleaner levels even when I cold start the PC and play for 2 minutes. I replaced 2x GPU's and a motherboard on warranty, and now the problem is off warranty, so I need to solve the problem myself :)) 

I saw a lot of information and differences between chassis. I tried every software and bios updates, the space shuttle still takes off my desk. 

So.. what are my options?

1. Change the top and front fan from crossair ML120 pro? Or its better with the sandwich - pull in and out - ?

Or 2 try to water cool the GPU with waterblock and external fans from articool? It seems a bit of hassle with this option, but I got no other option.. is this or throwing it out of my window :)) I got anxiety because of this PC! 

Maybe other options? Save a brother out!
