[2021] CPU Heat is a constant problem

I recently got a new PC, an HP Omen. I7-9 series CPU, 6GB graphics, 16GB ram, etc.

I put everything to low settings because I just want the gameplay and smooth FPS.

The problem is that the CPU keeps overheating to between 88 to 97 celcius. The game has crashed 9 times within a 100hours of playtime.

I just got done with the Irish DLC and was about to continue the main story.

So i decided to clean out my heatsink. It had no dust in the heatsink itself but the CPU was caked with dust underneath.

Ive done this many times before. Cleaning the dust and replacing thermal paste. But I screwed up and killed the motherboard.

The computer is coming back this week from repairs.

Can anyone give me help on reducing heat for this game so I don't have to repeat this problem again?

I think the overclocking did it. It went up to 4.6ghz. I was going to try reducing CPU power to 80%-90% when it gets back.

I'm worried that my fps stability will be thrown off though.
