I have a 1048 and it needed the impeller glued to the magnet because it made a very irritating noise. However all 1048s do not exhibit this problem, a friend of mine with a similar setup has had no trouble at all with his. I think it's because the problem only arises at a certain range of flow resistance in the system. I'm currently using a low pressure drop radiator from DangerDen and my friend used the DD Cube which basically points to either that the pump exhibits noise with lower resistance as the Cube in my friends system made the pump noise-less, but it could also be because of trouble with my impeller.
