CPU Cooling problems: Just like 95C is normal for Ryzen, 100C is normal for Intel CPUs in many workloads. If you're worried about CPU temperatures, please look at reviews for the laptop or CPU cooler you're using.

Hottest core 20 C higher despite contact frame (alien.top)

On my 13700k with thermalright contact frame, and Arctic Liquid Cooler II 360mm AIO, thermal grizzly paste, despite the contact frame which helped reduce the temps of all cores, P5 is still 15-20C higher than most of the other P cores. In XTU P4 and P5 are starred, so are the best performing onces. I undervolt by 0.115V. The "chips" rating by my Z790 Elite AX gigabyte motherboard is 93. Finally, I pipe in cold outside Canadian air to blow on open PC.

Any suggestions on what I can do to improve this? Or is this "Normal" All other posts I've read suggest this isn't normal.

Current temps on full load: P0 68C P1 71C P2 67C P3 85C P4 70C P5 91C P6 69C P7 78C. The E cores are all 62-64C. Clocks on full load: 5.3GHz all P cores. Power 195W Vcore 1.164V.

P3, P5, P7 are all on one side of the CPU, so it's likely the cooler pressure on the CPU IHS isn't even for some reason.

Some ideas:

Use more paste and make sure the paste imprint is even.
Double check to make sure you didn't mix the LGA1200/1700 standoffs which are different lengths.
Make sure the excessively large universal Arctic mounting frame isn't catching on a VRM component.
Make sure the contact frame tension is even across all four screws
