Intel's Core i9 10900K with ten cores apparently gets very hot under high load, even when using AiO (All-in-One) water cooling with a 240mm radiator. This is reported by user WolStame from the forum of the Chinese website Weibo (machine translated, via Twitter users) @ 9550pro).
According to this, Intel's new flagship for the desktop in the stress test reached over 90 degrees at the top and almost 90 degrees on average.
What do the test results say?
WolStame used the system stability test »Stress FPU« from AIDA64 for the test. HWiNFO64 is also used to check the temperatures and obtain information on the power consumption.
So far, a power limit of 250 watts has been assumed for the 10900K. In view of the test results from WolStame, this seems to be a realistic assumption. (Image source: Weibo / WolStame)
According to WolStame, the Core i9 10900K reaches a maximum of 93 degrees at 4.8 GHz on all ten cores and twenty threads, on average it is 87 degrees. It consumes up to 235 watts of power, on average it is 233 watts.
Although the CPU has not yet started throttling according to the graphics (see left image above), i.e. reducing the clock rate in order to meet the temperature limit, the values achieved should already be very close to the set limits.
The so-called Velocity boost, which Intel offers for its new top models 10900 (K, KF and F) and with which the highest clock rates can be achieved ex works, does not work at such high temperatures, which is why the clock frequency of 4.9 GHz on all cores in the Test could not be achieved.
Comparison values with eight-core CPU: In our own test, an Intel Core i7 7820X including water cooling with a 360mm radiator under stress FPU reached around 70 degrees with balanced, but clearly audible settings (fan and pump). In games, the temperature is rarely over 60 degrees. With quiet settings for the fan and pump, it is around 10 degrees more.
The Core i9 10900K, on the other hand, has two more cores and clocks significantly higher. At the same time, the leaked information does not provide any details about the exact settings of the water cooling.

Why is Intel exploring the limits so strongly?
It would not come as a surprise that Intel's new CPU flagship in the desktop area puts more power and temperatures than the Core i9 9900K, not least because Comet Lake-S (Core i 10000) is still in 14-nanometer process is manufactured.
Intel has been using this for six years. Competitor AMD, on the other hand, has been using a 7nm process from TSMC since Ryzen 3000, which is more energy-efficient due to the structural reduction.
Manufacturers generally try to find a good balance between performance (clock rate) and power consumption or waste heat to be cooled. AMD currently has advantages here that Intel can hardly compensate for without moving to a new production facility.
