FM3 noise issue

[EIRAIVAN]

When I turn on FM3, it is normal, but after 10 minutes the noise begin.
Has anyone else experienced this?

Is it the screen? Some of the screens on the the airplane I fly squeal like that at certain brightness settings. Try dimming the screen if that’s the case. Good luck

Move your ear all around your FM3. Does the sound get loudest at the vent holes?

Thanks for your reply. I think the noise is more likely came from the fan.
