I’ve had my R16 for about three years now. I had a lot of issues with it upfront with it blue screening, after a number of troubleshooting fixes that’s been resolved for a couple years without any issues.

Now, when fully turned off, it’s making a loud clicking sound every 5 to 15 seconds. Searching online I haven’t found anything similar. I’ve been unplugging it while not in use. The clicking also doesn’t seem to happen when turned on.

Any idea what this could be? Even if it’s not harmful I’d like to resolve it because it’s so loud I can hear it from the next room where I sleep.
