So after a week or so of running the liquid cooling unit. I found foam build up in my reservoir and i'm losing liquid. I've lost 1/4 of my liquid already. I'm not sure when the issue even started. I see no leaks or visible air bubbles in my line.
My thoughts *and this is why I don't do liquid cooling* is that you had an air bubble in the line, and it kept your liquid from flowing correctly and it somehow got evaporated. Start over, try it again with brand new liquid and keep a very, very close eye on it.
