Core i9-11900KF warmed up to 98 degrees under a liquid cooling system with a 360mm radiator

Insiders reported about the hot temper of Rocket Lake-S processors in the first reports on testing engineering samples. However, there was still hope that Intel would be able to slightly improve its 14-nm process technology and reduce temperature and power consumption. On the other hand, one could expect a worsening of the situation, the company had to adapt to the 14nm microarchitecture, which was originally developed for 10nm.

Apparently, it was not possible to improve the situation. According to information published on Chinese Forum ChipHellCore i9-11900KF in AIDA64 stress test with AVX512F instruction set heats up to 98 ° C while cooling the AIO with a liquid system with a 360mm radiator. This is at a frequency of 4.8 GHz and a voltage on the vCore cores of 1.325 V (the author of the experiment claims that CPU-Z displays an incorrect value). Power consumption has reached 250W – this is the PL2 level, which should turn on for a short time

The author does not give details, in his opinion, the terrible results may be the result of a still “raw” BIOS or very poor contact of the lid with the crystal. According to preliminary data, the frequency formula for the Core i9-11900K will look like this 3.5 / 4.8 / 5.3 GHz (Base / Turbo Boost / Thermal Velocity Boost).
