CPU Cooler Check

Socket hub

LGA1851 (Core Ultra 200S)

Intel's Arrow Lake socket. Same hole pattern as LGA1700, but the die sits further north so some vendors sell revised brackets.

Terms used on this page

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 (typically 95–100 °C, 89 °C on Ryzen X3D parts). At TjMax the CPU throttles clocks to stay in place; it will not overheat, but it will lose performance.
ILM
Intel's Independent Loading Mechanism, the socket clamp. On LGA1700 the stock ILM bends the long CPU package slightly, reducing cold-plate contact; contact frames replace it to improve temperatures.
