Process	32 nm; Sandy Bridge; 37.5 × 37.5 mm package; 72.6°C maximum case temperature, not junction temperature.	Intel 7
Cooler
Cooler	LGA1155 is incompatible with LGA1156. TechRadar describes the launch P67 chipset as supporting CPU overclocking and H67 as supporting the integrated graphics output; chipset choice affects available features. Intel publishes no separate maximum turbo-power figure.	Maximum operating temperature 100 °C; maker maximum turbo power 253 W. The 320 W Extreme profiles used in launch reviews are separate operating configurations.
