Hi I have delided and overclocked my 8700k to 5ghz and on HWinfo64 it shows Two of the cores being up to 20c+ cooler then the others when stress testing on prime 95 is this normal or could there be an issue somewhere?

Before the delid all cores was around 68c and with in 2c to 3c of each other when stress testing on stock bios settings.

Please see attached photo for the temps

Delid - with conductonaut liquid metal
cooler - corsair h100i V2
thermal paste on top of IHS - Artic MX-2
Motherboard - asus Z370F

Simple OC -
multiplyer 50
voltage 1.3
every other setting is stock

Those cores are not being used for some reason (from your screenie) so temp difference looks like coming from that

Remove Overclock and run at F5 BIOS defaults and see if all cores load up running prime

Your correct. My oc was not stable so some of the prime 95 workers stopped working mid stress test. I needed to add higher voltage to fix the issues.**And now all cores are around the same temp

Thanks for the help*
