The issue went away when I reloaded r53 firmware and came back with r57. I emphasize that the effect is very small and would be missed by most listeners except for some very critical listeners. One friend said it sounded like a clatter mechanical noise rather than a fan. Once you are aware of it, you hear it routinely. It's not a deal breaker, just an anomaly that might be explained and eliminated by the firmware guys.
