Hello board-

I've been running an Evercool water system for about a year and a half and it does a super job cooling a cranky 3.4 ghz Prescott. My question is this: Where the hell does the coolent go? I usually have to add coolant about once a month. I performed an extensive leak check; and I do mean extensive... I've been over it with a fine tooth comb. My coolant contains a little anti-freeze so I laid down some paper towels under the fan and pump assembly. I hoped that the colored fluid would end up staining the paper towel green and I would find the leak source. Nothing. The tubing, water block, pump and fan, the case bottom all were dry. My system operates very nice, and it's really not a big deal adding the coolant. It just bugs the shit out of me because I have no clue to where it's going. Any ideas out there?

thanx

It evaporates and escapes the system, of course. A water coolant loop isn't a completely closed system, usually; the pumps and other components have means of bleeding off excess pressure, which is usually caued by either coolant that has reached vapor point, or has just chemically broken down to a gas state over time, usually in such small amounts that it will be untraceable. Even phase-change cooling which IS a completely closed system eventually needs a refill of coolant. It's all normal.

Makes sense to me. Thanks for the response!
