...that's a solid steps (repasting, undervolting, AIO inspection, disabling E-cores) it’s apparent this goes beyond standard thermal variance confirm the AIO pump is running at full RPM and is recognized in BIOS or monitoring software, verify the AIO cold plate is making uniform contact with the CPU's integrated heat spreader. Uneven mounting can cause hotspot behavior , some LGA1700 sockets, especially with improperly torqued brackets, may cause uneven IHS contact. consider using an LGA1700 contact frame if not already in place. Check in BIOS your CPU lite load and PL1, PL2 wattage. I have 14900kf and 280 AIO paired with 32GB RAM and 3080. Temps full load OCCT max 80c with 5GHz pcore and 4GHz ecore. Playing Cyberpunk max settings 30% CPU load and temps around 60-70. In BIOS I have XMP 6600 and PL1, PL2 set to stock (253W) and CPU Lite load for "Mode 3". Before when I had XMP 6600, PL1 PL2 set to 4096W and CPU Lite load for Auto my pc was easy 100c in occt (5.6ghz pcore then throttling to 5.1Ghz) and around 80-85c playing cyberpunk with 30% cpu usage.
Soo yes yours temperatures are normal for this kind of processor, but it need's a little tunning to make it work good.
