Power behaviour of the Core Ultra 5 225

The Intel Core Ultra 5 225 is a Core Ultra 200S processor for the LGA1851 socket with a 65 W base power and a 121 W PL2 turbo limit. That is 1.9× its base figure, so a cooler chosen from the TDP alone will be undersized for sustained all-core work; this site rates every cooler against the 121 W ceiling instead.

On most Z-series boards the turbo window (Tau) is disabled, which turns 121 W into a continuous load during renders, compiles and benchmarks. In GPU-bound games the package settles closer to 65 W, which is why gaming temperatures are far lower than Cinebench temperatures on the same cooler.

Which cooler classes suit it

68 of the 70 coolers in the database ship with LGA1851 mounting hardware, and 62 of those (91 %) keep the Core Ultra 5 225 in the Excellent band with at least 25 W of thermal headroom under a sustained load.

By class: 19 of 19 dual-tower air coolers, 13 of 13 single-tower air coolers, 1 of 7 low-profile coolers, 15 of 15 240/280 mm AIO liquid coolers and 13 of 13 360/420 mm AIOs rate Excellent. The smallest cooler that avoids a throttling risk is rated 120 W (Noctua NH-L12S). The cheapest Excellent option is the Thermalright Assassin X 120 Refined SE at about $18.

LGA1851 mounting notes

LGA1851 shares the LGA1700 hole pattern, so 1700 brackets fit, but the Arrow Lake die is positioned further north. Some vendors sell revised brackets or offset kits that improve contact.

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.
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.
Thermal throttling: Automatic clock reduction when the CPU hits TjMax. A pairing is flagged as a throttling risk when the modelled full-load temperature reaches the junction limit or the cooler is rated 15 W or more below the CPU's boost power.
