x17 R2, performance issues after 8 months

My x17 R2 CPU has started to run really warm and is going around up to 100°C when just idle without me doing anything. I've tried just about everything I can think of updating everything, fooling around with the AWCC settings and even did a support thing and all they was tell me to unplug my external hard drive and that it's supposed to run that warm (which I know they are supposed to run that high when under load but when idle is it?).

Also have watched like a billion YT videos.

My performance has also tanked which as far as my limited PC knowledge is because of its throttling due to the heat. It could be something else for all I know. All I know is I shouldn't be getting 30-60 FPS with an i9 and a 3080 Ti when playing on medium-high settings.

The laptop is about 8-9 months old.

If anyone could help that would be greatly appreciated.
