PS5 Beeping Mic Issue with Console shutting off randomly after hours of play

Been Having a issue with my Ps5, I have had this issue for about 2 months now where my ps5 controller mic would work then all of a sudden stop working followed by a loud beeping sound. Only way to fix this issue is to turn of my controller to get rid of beeping sound and the cycle starts again. The other issue I am having is after playing for about 1-2 hours my ps5 shuts off randomly during games, I have to unplug cord and restart ps5 again. I have opened my ps5 and cleaned my fans with no luck on fixing the issue. Anyone have a clue on what I should do to fix this issue?
