Hey! You have the same shitty AIO that Comcast sent me! It overheated and tries to melt itself down all the time. Luckily it gets so hot that the adhesive melted and the screws were easily visible. I just took the chassis off and it mostly doesn't overheat anymore.
Crazy, the thing is basically hollow and was right next to the window and would still overheat. The bottom doesn't allow for any air intake so it sufffocates. Also it's 80% plastic because they couldn't be assed to add aluminum heatsinks.
