I'm trying to set up my first watercooling system here. The first try, almost every single joint leaked. After tightening the clamps alot, I got almost all the leaks to stop. The pump inlet was hard though; it has 3/8" threads and I couldn't get a 3/8" thread with 1/2" barb, only a 3/8" barb. 3/8" barbs and 1/2" hose do not work together well at all. The only spot left that leaked was the reservoir, (I made it from a 2" PVC Y connector and 2 plastic "test caps" because they didn't have real endcaps.... Real hardware stores suck. Almost as much as real computer stores..... but anyways, the reservoir leaked where the barbs went into the end caps, and at the edges of the end caps... after a several tries to fix it and only moderate success, I went overboard. And I mean overboard. I put on so much 'clear' RTV silicone that I could barely see the base of the barb, I had silicone past the end of the hose on the barb even.

And one of the barbs still leaked.... WHY!!!!

This is fun though, even if my reservoir is really an evil demon in disguise.

Later I'll put up pics of the pump/reservoir, but past that its nothing special, just a maze 3 and a dangerden chipset block, with a chevy caprice heatercore....

One other thing I've learned doing this: Its really hard to cut tubing to lenght when you haven't gotten a case yet (my computers been sitting caseless on the desk here for probably 2 months now) and you don't even know if you'll use a midtower or a full tower..... or maybe a cube.
