Terms used on this page

Thermal headroom: The cooler's sustained dissipation rating minus the CPU's boost power limit, in watts. Positive headroom lets fans run slower and quieter; 25 W or more is rated Excellent here.
PL1 / PL2: Intel's two power limits. PL1 (Processor Base Power) is the sustained draw the CPU settles at; PL2 (Maximum Turbo Power) is the short-term boost ceiling. Many desktop boards run PL2 indefinitely, so a cooler must be sized for PL2, not PL1.
TjMax: The maximum junction temperature the maker allows, typically 95–100 °C. AMD lists 90 °C for the Ryzen 7 5800X3D, 89 °C for the 7800X3D and 95 °C for the 9800X3D. At TjMax the CPU throttles clocks to stay in place; it will not overheat, but it will lose performance.
RAM clearance: The tallest memory module that fits under an air cooler's front fan in its stock position. Dual-tower coolers with less than 42 mm clash with tall RGB kits (typically 44 mm) unless the fan is raised.
