Desktop Intel Kaby Lake, apparently a very poor thermal interface

Intel is preparing to market Kaby Lake processors for the desktop segment. They have to fight with the new AMD Ryzen, although in the case of Intel the same is true for the previous generation (in this case, Skylake).

And the first tests on the Network indicate that Intel could step on the old rake in not the best internal thermal interface. Enthusiast forum AnandTech, hiding behind a pseudonym RichUK, got Intel Core i7-7770K and conducted a series of tests.

This CPU operates at frequencies of 4.2-4.5 GHz. It turned out that raising the frequency even up to 5 GHz (with a voltage of 1.34 In) is the future flagship is very difficult. Under load in Prime95 application dispersed sample is heated to 96°C. For cooling said cooler Corsair H110i.

The experimenter did not stop there and opened the CPU, removed the native thermal interface and replaced it by CoolLaboratory Liquid Ultra. After that in the same test, the temperature dropped to 30°! On average, the temperature of the new thermal interface became to 26°C lower than with the native. It should be noted that the RichUK was a retail sample.

It remains to wait for first tests after the announcement and see whether the situation is such. Of course, this kind of acceleration need not all. But Intel specifically has a separate line of CPU with an unlocked multiplier, which means overclocking. But while it seems that the process is complicated by the temperature regime.
