The Intel Core i9-10900K CPU has officially launched today and has already achieved some great overclocking feats. Renowned overclockers from around the world have pushed the chip, on the accompanying Z490 platform, to the limits.

In our review, we have found the Intel Core i9-10900K to be an impressive overclocker, hitting 5.2 GHz across all 10 cores and 20 threads. But unlike professional overclockers who have access to the LN2/LHe cooling apparatus, most tech publications are limited to standard liquid or air coolers. Since LN2 provides temperatures below freezing point, the CPUs can be pushed much higher than on standard coolers.
