Thermalright Peerless Assassin 120 Black Dual Tower Air Cooler

Exceptional cooling at a great price

Easy to install, quiet and keeps the temps on a 7600X low.
It's quite big so make sure you have room.
And depending on your motherboard, you may require low profile RAM, like the ADATA Lancer Blade I purchased from Orbit.

Solid cheap CPU cooler, easy to install with plenty of guides to help
