ASRock X570 Phantom Gaming 4 Motherboard Temp Wrong?

I've got a ASRock X570 Phantom Gaming 4 with a AMD Ryzen 7 3700X 8-Core Processor.

I'm running Windows 10 (v1903) and HWiNFO64 version 6.34-4300

When running HWiNFO the Motherboard temperature reported appears to be a rounded copy of the SB temp?

If I use the ASRock Phantom Gaming Tuning app, it shows the Motherboard temp as around 30C, but HWiNFO shows it around 60C.

The 30C is also reflected in the BIOS as the MB temp.

Is there another temp I can monitor in HWiNFO that might be the MB temp as reported by the BIOS?

I'm trying to set up new fan speed graphs and it took me a while to work out the MB temp was no where near 60C, hence why the fans were not spinning up.

You have lots of values hidden. Can you please look among those hidden if there's a value matching the M/B temperature seen in the Phantom Gaming app?
I’ve had a look. Nothing matches exactly.

I had hidden values based on type, so I’m still seeing all fan speed and temp values.

I can take another screenshot/debug with all values on if that helps?
