I have a ViaAqua 1300 pump in my water-cooling rig, and the pump has suddenly gotten rather loud. It used to be much quieter than all the fans, now it drowns them out. I even have to unplug it at night because of the noise, where I used to leave it on without being able to even hear it. Has this happened to other people with this kind of pump? I haven't had it that long; maybe 4-5 months. Does anyone have recommendations for a better pump?
