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.	LGA1155 motherboard compatibility depends on chipset and firmware; Expert Reviews advises confirming older 6-series board support with the motherboard maker. Intel's current specifications give no separate maximum turbo-power figure.
