Keep in mind that the 5600x is only a 65wtt TDP CPU .. I run the be quiet! Dark Rock Slim on my daughters 5800x and it works great. That being said , you might want to invest in 3600'ish speed RAM (preferably 2x16GB sticks over 2 or 4x8GB sticks) to get the most out of your CPU's Infinity Fabric .. or a better GPU (I don't know you system specs so just throwing stuff out there)...
Invest in a good PSU to provide good clean stable power to all your pieces and parts ..Gamer's Nexus has an interesting video on that:

Make sure you have good air flow because it's important to keep your VRM's and RAM cool too to get the most out of ALL of your parts
Maybe grab a PCIe 4.0 NVMe SSD drive for your OS and another for your games ..
CPU cooling is very important .. but there are a lot more things to consider in your total system build to get the most out of the WHOLE setup
