The prior owner was a teenager, so you can do the math about why it was this bad. But I also have to say that Sony clearly made so many design flaws with the “fat” PS3. The shape of it was clearly meant for aesthetics, and not function. There are so many hidden places for dust to collect, and the airflow pattern isn’t optimal. These things are notorious for overheating.
Even after I cleaned it and replaced the thermal paste, it still runs pretty loud.
Unfortunately, a ton of games are still locked on the PS3 and not even available on PS+ Premium streaming, so having a PS3 is one of the only ways to enjoy those games (besides emulation).
Seriously do people just live in a trash heap? You see this so often. My day one PS2 is still immaculate inside and it’s only ever been cleaned inside once in 23 years. I’m glad you got it all cleaned out. I hope you did it outside.
