Question 3 year old i7-8086k running in the 80-90c range now

I bought a i7-8086k just a few months over 3 years ago. Had no issues with this CPU until recently after relocating the computer to my friend's house. Her office space is quite cool and definitely more spacious (way more room to breath) than where my PC was previously located; figured I might see slightly lower temps than previously experienced before however I noticed on Halo Infinite I am seeing temp readings on my ROG Maximus X Formula in the 80c -89c range when under load and mid 50c at idle. NZXT cam is showing a 10+ degree difference, not sure which to trust but I have reapplied thermal paste twice from the initial application and dusted out the H700 case but no difference in temps. Worried I'm gonna fry my CPU, any insight, advice or tips to diagnose?

Build sheet:
Case: NZXT H700 (4 120mm fans, cooler excluded)
MB: ASUS ROG MAXIMUS FORMULA
CPU: I7-8086K (clocked at 4300Mhz)
GPU: EVGA GTX1080TI SC2
RAM: Kingston KHX2666 2x8 GB
CPU COOLER: NZXT KRAKEN 120MM

Yes, Noctua 12a. Go air, 8086k doesn't need water and you won't need to worry about pumps failing or air pockets forming from moving the case.

Care to elaborate a little further? Also might you know why my LED screen on my MB and NZXT are showing readings that are 10 degrees apart and which is likely to be more accurate?
