I own a swiftech 240x prestige edition and it's only 2 weeks old. I've noticed significant drops in water levels over the use and the water line has dropped down half of what it used to be. I've noticed during shipping the styrofoam was a bit moist, but i assume it's probably due to the fact that the jostling of shipping an item from downstate would cause. I've also noticed there is steam in the cooler, even though the CPU is not even hot yet to the touch. I felt around my components to make sure no liquid got on it but it was suspiciously devoid of liquid.
