Is it normal for water-cooling systems to make occasional bubbling sounds? To the extent whereby you're convinced you have an aquarium in the room, even though you don't? I've had this machine since 2006, and have never heard it do that before... It will bubble away for a day or two, then just stop.
I've always been a little dubious over water-cooling systems, ever since I had to have the previous one replaced after receiving my ALX with all its water-cooling tubes broken, and the fluid splashed all over the internal components.
