For running stock the Ryzen 9 3900X doesn't need a big cooler strapped on for maximum performance and it certainly doesn't require liquid cooling. However, the Intel processors don't come with a cooler and they demand a rather good one.
1. NZXT KRAKEN X62 – Best CPU Cooler For Ryzen 9 3900X. The powerful NZXT KRAKEN X62 is one of the most popular and best performing CPU cooler for the Ryzen 9 3900x and is likely to feature in the exquisite builds.
As a matter of fact, every Ryzen 7 and Ryzen 9 CPU come packed with the Wraith Prism. Athestitaccly, the cooler has a dual LED-lit ring with a transparent fan in the center with LED lights in the fan hub. Thermal paste is pre-applied at the factory so the cooler is ready to go right out of the box.
When comparing the Ryzen 7 CPUs to the Ryzen 9's, the Ryzen 9's are the clear winners. They provide a higher number of frames per second (fps) overall. The Ryzen 7 3700X provides 156.1 fps and the Ryzen 9 3900X provides 159.7 fps.
So, the Ryzen stock coolers are pretty decent, and they even allow for some OK overclocking as well, however, I would NOT recommend getting it if you wish to overclock heavily, in that case I'd recommend getting a decent water-cooler or a good air-cooler.
Stock air coolers that come bundled with processors have not been terribly exciting over the years, though to AMD's credit, its Wraith coolers for Ryzen CPUs are pretty good. In mainstream territory, it's good enough for all but the 16-core/32-thread Ryzen 9 3950X.
there is no gpu built into the 3900x. so you need a graphics card to get ANYTHING to the screen.
