Question gpu underperforming

[Naveents]

my pc has ryzen 7 2700x with rtx3060(ibought it recently this month a week ago), i have been playing spider man pc for 3 days keeping it in high graphics ,today i faced increased temperature and fan speed compared to last two days and even had few frame drops ,ialso get some type of burning smell even when iam not gaming,
i hvae upgraded my gpu from rtx 2080 to rtx 3060 since my old one was heating up unmanagable heat and my monitor was turning off and was not at all able to use it for basic editing as well and gta 5 couldnt run even at the lowest graphics setting

Was that new or second hand when you got it? Could it have been damaged by Data Mining or the cooling internals blocked by dust etc.
