Had my series x about 4 l years now and still he last few days it’s been super noisy and even started shutting down on one certain game after like 10mins due to over heating. so I popped the back off and fuking hell there was some amount of dust in there so got me toothbrush out and gave the heatsink and fan a fuking good clean and it’s been running silent since like when I first got it. deffo recommend giving yours a clean too if you’ve had it a few years it’s really easy to do
