I just built a nice system, and as I look at it I can't help wondering if I made a mistake by using an H55 liquid CPU cooler? I look in there and that cooler and radiator are poised just above my 2 gtx 780 cards. If that thing springs a leak, ever, all those components are down the drain!! What is in the liquid cooling? Is it a non-conductive fluid? Or is it just a question of time before something wears out like in a car?
