Some idea of overclocking potential Kaby Lake processors in LGA 1151 allows you to get our previous material . In particular, the engineering model Core i5-7600K enough air cooling and voltage 1.504 V, to conquer the frequency 5.1 GHz.
As recognized by colleagues EXPreview site, Core i5-7600K processors were seen on sale in a Chinese online auctions, and on older model Core i7-7700K can make reservations. Since these processors can work in motherboards based on the Intel logic "hundredth" series, the availability of processors should be available to please the Chinese enthusiasts.
Colleagues suggested exploring appearance Core i5-7600K processor in comparison with the predecessor generation Skylake, the role of which was elected Core i7-6700K (pictured right). As already noted, the processors Kaby Lake typical tides got heat spreader lid. This is at least a little, but increases the CPU cover the area of ??contact with the bottom of the radiator.
Measurements of the thickness of the PCB substrate leads to the conclusion that it does not become more than the Skylake processors, and remains approximately equal to 0.8 mm. At the processor lid has a height of 4.26 mm, but we would not say that it has become higher, because the height difference with skylake (4.21 mm) may be due to measurement error (0.05 mm).
