Finally all done! Loop sequence is as follows: Res>CPU>GPU>3x120mm rad. All works perfect, it is quiet and relatively cool. I got 32 dB and CPU/GPU=35C on average using and 40-45 dB CPU~65C GPU~50C under heavy gaming 2K resolution (ambient 27-28C). Also I'm using Alphacool quick release fitting as a drain port, no need in ball valve or other fittings. So I'm pretty happy with the results.
Any thoughts please leave a comment. Thanks!
High quality as expected from ASUS!
Three stars only for average customer service. Overall works fine, relatively quiet. The only problem was incorrect tubing connection to the CPU block. The quick release fitting must be connected in such a way that the red end means "out" flow direction and blue "in", unfortunately it took me a lot of time to reconnect everything and to integrate it in the same loop with Eiswolf GPX.
Looks great and does the job. It keeps my GTX 1080ti at 50C under load.
