Aurora R8, Temp and Usage Spikes

I've never used this before, but I'll give it a try. I have an Aurora R8 with a RTX 2080, i7-9700k, and 16gb ram. Whenever I play games, my CPU usage will spike to 100% whenever I go into a game and my GPU usage will be around 80-90% usage. My memory usage will be around 80-90% usage, and my power usage will spike to very high in task manager. I know I have good specs for my PC, so I'm really confused as to why my pc can't run games without it being really loud. Even when I turn the details and video settings in games all the way down, it still doesn't do anything. On top of that, about every two minutes my pc will start to rev up as if it's gonna explode. It'll do that for a few seconds then go back to being relatively loud. When I play games I usually have edge, discord, and my game open. (Apex Legends, Overwatch, League of Legends, etc. are the games that do this to my pc) This never used to happen and now it is. It started around the beginning of this year. I've had this pc for about 2 years. Anyway I can make my pc sound like its not about to explode?

Thanks,

Matt
