MonstieurI have a 10900X and EVGA CLC 280. Some cores exceed 100 C during stress testing when overclocked to 4.9 GHz @ +35 mV. The 10920X being a better bin with higher Turbo frequency might overclock better with lower voltage, but the 2 extra cores will definitely add more heat overall. The 10920X is still the better chip and in the worst case you can disable 2 cores in the BIOS. With a strong liquid cooler, these CPUs only overheat when running stress tests. You can run 5+ GHz all-core and not overheat in real-world applications & games, so you can even get a 10940X. I wish I had gotten the 10920X with a better bin after seeing what a great overclocker my 10900X is.
MonstieurTemperatures are a non-issue for gaming / desktop usage. You can get any CPU and it will run below 70 C.
MonstieurThat's a weak test. I use LinpackXtreme and Prime95 and it hits 105 C.
