xerzex Posted August 17, 2008 Share Posted August 17, 2008 Hi All, I have had my HX620W for about 9months - however in the last 1-2months, it has started a "humming" noise - it seems to pulse. I had moved the PSU into my test system, and the same noise occurs. I have tried everything, inc stopping the fans. Any ideas what it could be? The noise seems to be like this: Hum (2secs) silent Hum (2secs) silent and so on.... is a RMA required? Link to comment Share on other sites More sharing options...
