My pc is getting unusually loud and my monitor turns off.

So basically when I play almost any game (mainly ff7 rebirth right now) silent hill, even Roblox it doesn’t matter, sometimes my pc starts becoming so damn loud and I’m way above the minimum requirements for the game. For info I’ve got a rtx 3070 and I’ve heard that it’s known for getting really loud because of its aggressive fan curve. But that’s not all. As soon as my pc becomes loud during any game, my monitor suddenly turns itself off and the excruciating loud noise from my pc never stops and I can’t do anything so I have to turn it off. I’m also thinking that this could do some damage to my pc overtime but I’m really desperate for answers. Help much appreciated.
