I was playing rust with my friends in discord and I have a omen obelisk prebuilt gaming pc with I7-9700, RTX 2070 Super, when I started hearing a loud high pitched sound that got progressively louder over about 30 seconds, it almost sounded like a siren. it started getting very loud and I started to think it was going to explode so I turned it off, I checked the Cpu temp and it was at 80 degrees Celsius. But I’m not sure if that was the reason it was going off
