CPU Temp#4 showing as 105 Celsius! All other temps appear fine

[techsupportgore]

Hey Guys,

I'm hoping some of you may be able to shed some light as to whats going on here please.

So I built a new machine yesterday (same PSU and GPU, specs below) and looking at HWMonitor the CPU temp #4 is showing as 105c...all others vary around 20-30c

The BIOS CPU temp is showing the average of all 6 temps at around 38-42c

I've reseated the heat sink and went through another round of applying thermal paste but the issue persists.

I haven't bench tested it yet, but I will soon and update you all with my results.

Any ideas on what this could be? Possible sensor issue? Or am I missing something here?

I just cant seem to find anything online with anyone else having the same issue, though if my google skills suck please let me know by providing other users experiencing the same thing so I don't have to waste your time!

Appreciate any assistance here guys. If I've missed anything just let me know and I'll provide what you need.

Specs:
AsRock Z270 Extreme4
I7-7700K (Heatsink: Noctua NH-U14S)
GTX 770
EVGA 600W (Will up it once I get my 1080ti)
32GB RAM
2 x 500GB SSD - Samsung 850 EVO
2TB HDD

Probably a bad sensor. You would probably be fine just monitoring the other core temps and using it, but since its brand new i would RMA it.
