Before you buy or sell a used Ryzen 9 5900X
Two variants can cause confusion in listings: the OEM Ryzen 9 5900 from prebuilt machines, which is a 65W part, and the later 16-core 5900XT. Confirm the exact 12-core, 24-thread 5900X stamping on the heatspreader before buying.
Rated at 105W with a 4.8GHz boost and no integrated graphics, the retail box never included a cooler. Budget AM4 boards with weak VRM heatsinks can throttle under twelve-core workloads, and you should verify all underside pins are straight.
