Hi, I have a Antec Kuhler h2o 620 cooler. Today I noticed there was a little bit of leaked fluid from my cooler. The input fitting to the radiator had some liquid around it so that is where I am assuming it came from. My question is what type of fittings does this cooler have and how would I tighten them? To me it looked like toothed fitting so I pushed the tube in a little bit but I don't know if it worked yet.
