Intel 12700k - two cores overheating and thermal throttling

[ykhan2019]

I have just replaced an air cooler with an Artic Freezer II 240mm AIO. Is it doing very well but under synthetic load using multi-core Cinebench R23, two cores are consistently over heating. On the basis that all P-cores are equal as this test is stress testing the system to 100% CPU. Is this a Thermal Paste issue? I can't find a schematic but imagine they are near the edge? Any thoughts? 90C was the expected outcome from Arctic.
