Process
Process	22 nm; Devil's Canyon, a Haswell refresh; 37.5 × 37.5 mm package; 74.04°C Tcase limit, not a junction-temperature limit. New polymer thermal interface and additional capacitors, described in Intel's Computex launch coverage and the exact-model reviews.	Intel 7
Cooler
Cooler	Intel lists both ordinary boxed and explicitly fanless boxed SKUs; cooler contents should be checked for the particular package. Compatible Intel 8- and 9-series chipsets require the appropriate motherboard BIOS. Intel's June 2014 fact sheet confirms volume availability that month; the announcement itself is not used as the on-sale day.	max operating temperature 100 °C; thermal specification PCG 2020A
