    Noise coming from Pro 12?

    The unit on my dash makes a humming sound. Sounds like a fan is running? Very Strange.

    I know it sounds crazy but my 12 Live did it and now my 12 Pro does that.
    I was told it has an internal fan.

    Thank you for your feedback. When I first heard it I thought its was a bilge pump or something. But I narrowed it down to the drivers console. All accessories switches are turned off. I have all electronics on a Sea Clear harness. I turned that switch off and it stopped. I’ve never heard that sound from the two 12’s on the bow. I wondered if the dash 12 runs hotter because I cut the dash and flush mounted the unit? I did not want to use a gimble mount on the dash.

    My old Live and now my new Pro were gimble mounted on the dash and they both hummed.
    I am very surprised no one else chimed in on this subject.
