The short version of the story is I was too cheap to by additive to keep algae and stuff from growing in my water cooling system and is has come back to bite me in the ass. My computer which has been in a closet while running for the last 3 months stopped working yesterday. I discovered that my watercooling loops had some algae in them and one of my water blocks was completely full to the point where almost no water was getting through. I am going back to air for the time being but would love to salvage as much as possible as watercooling isn?t cheap. What is the best way to go about this? I think I am going to have to toss the radiators regardless of what I do. Any advice is greatly appreciated. Thank you.
