My first attempt at custom water-cooling
This was quite the adventure; I went custom water-cooling mostly because of the gpu - a 5700xt strix - because I couldn't cool it even with a kraken g12 kit, staying at 110c hotspot and 50c edge at around 320w.
The cpu is a 3950x, staying at ~80c at 210w, and the hotspot of the gpu now also stays at somewhere near 80c (48c edge), after applying liquid metal, when pulling ~400w in occt after the water gets heated up (2250mhz set @ 1.237v). Without liquid metal, I was getting 110c around 350-360w (could have also been because I didn't tighten the screws as hard as after applying lm).
As for the gpu memory and soc vrm, I cut the metal bracket that was sitting on them with the stock cooler just enough so the water block fits. The core vrm is cooled with some little heatsinks, thermal tape and a high revving fan beneath the vrm; this cooler also blows air around the gpu, which also cools the memory quite well.
Overall, I'm happy with the results, especially because all of the components except the radiators were bought from AliExpress. The total costs of the loop were ~200 euros.
