My venerable series 4 is dying. It's been pixelating/hanging/rebooting about weekly for a few months. But, today it's stuck on the "starting up" screen. I suspect the HD is near death. I need a new device. But, I'm pathologically noise sensitive, and the device is in the bedroom. My prior series 3 I had hacked with a quiet fan. The series 4 (XL) has been reasonably quiet. So...how does the base fan noise of the Roamio compare to the Premiere? And, of the two devices, is one clearly more reliable? I will need to do something soon. Any advices would be appreciated.
