ICE-DWB12 - got it second hand with already delidded 13900KF.
Currently running 5.6GHz on six cores, 5.7GHz on two and 4.5GHz on sixteen at 1.32V.
It is not optimal at all and I will probably drop to 5.6GHz all P-core as that needed much lower...
Definitely liquid hellium overclockers will be interrested in 14900KF to break some records... https://hwbot.org/benchmark/cpu_frequency/halloffame
Otherwise not sure who will have cooling for this CPU
I run my 13900KF with direct die water...
It is funny people don't mention PSU
Power supply is fundamental system component - especially for these CPUs
Imho it is Intel's design flaw to release 300+W CPU especially given motherboard manufacturers on one side cut costs on good components...
