Asus maximus xii hero Stuck in LN 2/CPU overheating

Asus maximus xii hero (wifi)
Intel I7 10700k

Just built a new rig. Created my raid volume, installed OS, and started installing mobo apps.
Everything thing was running great. I installed Asus suit and was prompted to update BIOS. Ran the update, pc automatically restarted, and upon reboot i get a cpu over temp error.
Temps after the update are now running between 85c and 90c, will not come down.
I went back and checked the BIOS version and found a later version, updated again via USB.
Once the update is complete I'm prompted to recover BIOS settings. While in BIOS fresh from update temps are perfect. Once I attempt to boot windows the temps go right back up.

Any ideas on a fix here?

I did notice the mobo is stuck in LN2 enabled.
The board doesn't have a switch nor can I find it in BIOS.
Any and all help will be greatly appreciated!

Also using NZXT Kraken X72 AIO

I see you are looking in other fora as well for an answer.
Have you seen in the Manual page 2-10 the warning about connecting only 4-pin power plug?

Yes, I did. I connected the 8 and 4 pin upon installation. I also have a case started with asus and they are concerned bios update may be corrupt. Thank you for your response!

I know it sounds dumb but I gotta ask, did you take off the plastic film from the processor heat sink and apply thermal paste?

All protective film was removed from water cooler and cpu upon installation lol. Thank you for your response!

and from a cold start, after the PC has been off for say overnight, there are no CPU over temp warnings then?

Cpu warning temps come immediately. No matter how long it's been off. From a cold start it will boot at 83c.
