I have a delidded i9 7900x bought 3 years ago overclocked to 4.7Ghz at 1.19V. This year I did a hard tubing build also changed the motherboard to a Asus Rampage Vi Extreme Omega, however I am know getting very, very high temps on only 2 same cores at full load these are cores 0 & 5 they will hit 90c within seconds while the rest stay in the low 60's ? This was not happening before this hard tube build, I have reapplied thermal paste 3 times even reapplied the liquid metal between the die and IHS and even tried a different cpu water block but no luck. Is it safe to say the cpu's gone bad and those 2 cores are pretty much no use?

CPU gone bad?

Get rid of the liquid metal, clean it off and put normal thermal paste back in-between the IHS and die. See what the results are like then, it could be that the CPU has started to show a failure.
Do you have any other boards you can test with?
Thanks, no I don't but could it be the motherboard? I mean can a motherboard heat up certain cores?
Power delivery to the CPU is done through the socket, and each pin plays a role in that. A bad VRM component or management of the power delivery to the CPU can cause these issues.

Have you had those temps ever since the new build? Only ask as you say 'this year' you did the build, but you are 'now' getting high temps? Sounds like the lid of the CPU may not be making contact anymore on those particular cores maybe?
I reapplied the liquid metal also, when I saw the high temps but still the same.
