I see, I also played tons of RDR2 but I think it's quieter than what you describe. Mine was bought a year later so maybe they improved it in some capacity. Anyways, happy the new consoles are quiet at worst and silent at best.it was a launch One X and I played the fuck out of it. Easily my most used console of the entire last gen thanks to Red Dead Online, and you would only really hear it when I was playing Red Dead, which is obviously a demanding title.
Still, even at it's loudest it was nowhere near the jet engine that was my PS4 Pro at any given moment... so happy that's over.
Same with my setup. Can't hear my X, while my PS5 has a constant, annoying fan noise whenever I start a game.PS5 is far louder, both with the fan and coil whine. Series X has a very quiet fan whisper under load but it's really not noticeable.
