Could this be it when looking in HWiNFO64? (I'm currently running stock with a high workload)

I'm not trying to kill another motherboard this week - I promise.

A dedicated "VRM temp" sensor under motherboard sensors is only if the manufacturer places a visible thermistor in the VRM, next to the mosfets - and chooses to make it available in software.

You can just look at the VR Loop sensors, they're pretty accurate compared to the dedicated sensor on my Aorus. I think all boards with the new Renesas RAA229004 (B550I Aorus AX, B550I PG ITX) have the same list of sensors.

The top category is only for the Vcore portion of the VRM (6 phase x 90A ISL99390). The lower category is for the VSOC portion of the VRM (2 phase x 90A ISL99390) - if you have a non-APU Ryzen then you'll never see the SOC draw go past about 20W, easy to tell which is which.

That Auxiliary must be something else if its a valid temp... as its frozen on 46C like the 2 AUX below it (105C, 104C)
You can always search thread history on HWiNFO forums for more info, and maybe ask for any kind of help or clarification about anything.

As said VR Loops sensors on Aorus line is pretty accurate at least for temps.

SOC VRMs on my board (green box) are actually a little warmer at low/middle loads, probably because of the crappier heatsink on them.
Core VRMs have a real (fin) heatsink on, instead of just a chunk of metal.

EDIT:

Side note

If you want that BUS clock to get to 100 from 98.6MHz you can disable Spread Spectrum into BIOS.
Free ~1.4% boost...:D
