I just bought 2 stream 6000s, and one is making a weird vibration. If it touch it and move it, it'll go away for a minute but then come back, is the prop out of alignment or something? Its not a high pitch sound but rather a lower pitch that varies in pitch alittle. Not sure if this matters either but the one that doesnt make any noise is on a magnet mount and the vibrating one is on the standard mount.
 
They magnet mount with the rubber feet does tend to dampen vibration. It could be the bush bearing is loose. Try taking the pump apart and check that the bush bearing is fully inserted and give the drive unit a firm push in as well. They also tend to quiet after a couple weeks of running.
