Thanks for looking up the part numbers on the cooler.The math is a no brainer. The bigger the cpu, the bigger the cooler needs to be. That i7-8700k is as big as it got for that generation, it's not going to work out well using the stock cooling solutions, especially an intel E97375-003 which was built for the lower wattage i3/i5 cpus but often shipped with the i7-6700T/7700T/8700T. Never the i7 K cpus.
