Intel Rocket Lake-S sample runs quite hot - even with watercooling

Another post to take with a grain of salt. Bit Tech came across a post that shows some results from Intel's upcoming Core i9-11900K processor. Someone named "Enthusiastic Citizen" claims he got his hands on an engineering sample and he posted screenshots at the Asian ChipHell board.

What pops out is the thermal performance of this new 14nm chip -- and not in a good way. The sample was stressed using AIDA64 and hit a temperature of 98°C when cooled with an "entry-level" 360mm all-in-one watercooling solution. That's without overclocking, hopefully it stays chilled when doing more basic stuff like australian online casino. Of course, Intel isn't in an ideal situation right now as they're still stuck on 14nm and this is leaving the firm with less levers to pull if they want to compete with AMD's Zen 3-based CPUs. Intel is going for single-threaded performance crown, which may come at the expense of power consumption and thermals.
The screenshot isn't the clearest as it is quite low resolution. I've embedded it at 100 per cent above if you click to enlarge. You will be able to see from squinting at the image that the ChipHell user appears to have ran the Core i9-11900K through the AIDA64 stress test, with FPU option selected. The user seems puzzled with the result and isn't sure if the poor thermal performance of the CPU is due to its own intrinsic qualities or poor BIOS optimisation (system is using an ASRock Z490 Steel Legend). CPU-Z appears to report the voltage incorrectly at 1.4V, while HWinfo reports it is 1.325V. Another misreport by the system monitor tools is that this is a 'KF' suffix CPU, when the forum poster claims it is a 'K' chip.
The Rocket Lake-S processors are expected to be released in March. It will be interesting to see whether the retail parts run as toasty as this engineering sample. Rocket Lake-S is the final 14nm processor from Intel. This LGA1200 model features up to eight Cypress Cove cores, Xe-based integrated graphics, 20 PCIe 4.0 lanes, and USB 3.2 Gen 2x2 support.
