Thank you so much for answering! I guess this was doomed to end like this. After all, everybody would cool their pc like this if it was this cheap. I filled the loop with two of my friends holding the components at different elevations and poured water from the top until the tubes were full to the brim. I was aware of corrosion problems, but since I got all the watercooling parts practically for free I thought I'd try it out. If I invest in actual water cooling I might get ek fittings though, these ones are propably zinc covered steel. I wonder if I damaged my card by doing this? I've experienced some random green static on the screen occasionally. I read somewhere that it is not safe to run a loop at 80c :/ Would 240mm radiator be enough for my card? Thank you!

I got a coolermaster ML240 AIO for free with my new motherboard. At the same time I bought a 1080ti on Ebay, and to my surprise it came with an EK waterblock pre-installed. I took it as a sign and went to the hardware store to get some 9mm tube, fittings, and distilled water. I sliced up the AIO with a kitchen knife and built a loop. The water flows from the pump to the GPU, then to the radiator and finally back to the pump. It worked fine, but not quite as well as I expected. I'm Idling around 25c in Finland, where it's 0c outside and 18c inside my house. I can play light games in 4k and never break 50 celcius, but cranking everything up in Sekiro or Dark Souls 3 results in a slow creep into 84 celcius. I'm talking about an hour of play time before hitting 80c. At first I thought it might be the pump not working, so I turned it off. As soon as I loaded up my file in Sekiro the GPU jumped up to 80 so I quickly mashed alt+f4 and turned my pump back on. So the pump is fine. I've been turning the system around like a tumbleweed to see if there are air bubbles in the loop, but I'm pretty sure there are none. I got Noctua fans from a friend, but running them at 100% had no result other than being super quiet. Could it be that I need a bigger radiator? Or is the pump too slow? I'm using hardware store fittings that I believe are meant for pressurised air, but that cannot be a problem, right? Also should I get a reservoir? I don't know what those do. Thank you for your help.
