Crazy! Open loop water loss system. So I have always been a custom loop system man I am thinking about building a system for my soon to be new i9 and gtx 2080ti. The water cooling will literally just be plain tap water through a filter and straight in through my loop, out the loop and straight into the drain (to my water tank). Points to note. I dont pay for water, as it's part of my lease and the environment will be fine because it will be re-used from my tanks. Foreseen advantages are no radiators, pumps or fans. So system noise will be down. No pump to fail. Cons would be the system would not have any antibacterial in it. Which I believe I could add via a bellow if the system was to sit for long periods. If the system had a leak it would LEAK! But insurance should cover that. Opinions, discussions, any comment! Whack them below.
