Following the Core i7-7700K and Core i5-7600K Ultra, Pro and Advanced, the story now repeated with the Intel Core i7-8700K, where Overclocking expert “der8auer“, in collaboration with CaseKing, has announced a new line of processors alternative to that offered by Intel itself, confirming the arrival of an Intel Core i7-8700K Ultra Edition.

This CPU is obviously an Intel Core i7-8700K, but it has been tested to ensure that it reaches 5.20 GHz without any problems. It all starts by replacing the CPU IHS, replacing the poor thermal compound with a liquid metal thermal compound for greater heat transfer, which will enjoy perfect contact using a new IHS made of 99.99 % silver, so it will help to transmit the heat much faster to the cooling system, avoiding high temperatures. Silver provides a thermal conductivity of 430 W / m K, while copper remains slightly below to 400 W / m K.

Obviously, this has a price, 869 euros, almost double the price of Core i7-8700K.
