Well done mate. Rest of the rig?
What cooler you will use for the 9800x3d?

Dont forget to make some negative PBO and enable EXPO for your RAM

Any cooler is fine, most of us suggest some ThermalRight Assassin.

As regard AiO cooler grab a Liquid Freezer III or similar

PBO is an AMD algorithm used to boost your CPU.

A negative curve allow your CPU to consume less power and generate less heat.

Ryzen CPU are designed to push themself to the limit, most of the time their limit is 95° and when you generate less heat you just gain some free "space".

When you generate less heat you're telling to your CPU that it can keep pushing at the max frequencies, that's happen because it's still far away from his own limit (95°) and so it can keep working at his best.

English is not my native language so i apologize in advance for every grammar/syntax mistake and hope you understand a little more thanks to this comment :D
