Gigabyte 3080 Memory Junction temp vs Asus Strix 3080 VRM temp

Sooo from what I am reading online Memory Junction temp is the VRM, but this seems impossible. My gigabyte 3080 open air mining has a Memory Junction temp of 103-105 at 100 MH/s on HWINFO and reports it as VRAM on Nicehash.

Nice hash claims my Asus ROG strix 3080 in a computer has a VRAM temp of 96 at 100 MH/s, this is also reporting the Memory junction temp.

On HWINFO for my ROG strix card it tells me I have an Embedded Controller (EC) sensor it can draw data from, in sensors it displays "GPU VRM temp", the VRM temps while mining 100 MH/s claim a max of 55c….

So what is memory junction temp, and is HWINFO reporting my Asus VRAM correctly?
