Is default CPU core voltage too high? 7600x on ASUS B650-PLUS WIFI

I build two identical systems for my daughters.

Both contain:

• AMD Ryzen 5 7600x Cpu
• ASUS B650-PLUS WIFI
• G.SKILL Ripjaws S5 Series 32GB (2 x 16GB)
• Noctua NH-U12S Coolers
• Both PCs have different GPUS (but removing them didn't change voltages)
 
With both systems set to default bios settings, PC1 has a CPU core voltage of 1.4+ volts, while PC2 has a CPU core voltage of 1.2+ volts. Isn't 1.47 volts way too high?
Things I have tried:
 
• Both motherboards on latest stable BIOS of 3067.
• Swapping RAM between the two computers
• Repasting PC1
• Clearing CMOS on both PCs multiple times
• Removing discrete GPUs
 
I was hoping someone could give me some guidance on anything I should do here.
 
Thanks very much.

1.47vCore is absolutely too high for the base 4.7GHz of a 7600X. That might be something you see overclocked at peak frequency, but not sitting idle in BIOS.

I would swap the CPUs between the boards. If the 1.47vCore stays with the board, replace the board. If it follows the CPU, replace the CPU.

Well, I swapped the CPUs, and the high court temp followed the CPU. I still have 5 days of Newegg return left, is that grounds for an RMA?

If it's 1.47v at default speed, what is it under boost? Is the chip stable under a full core load? Are the temps manageable or does it hit thermal limit? You could always try reducing voltage using negative Curve Optimizer but that could also introduce instability. It would seem to be a very poor piece of silicon if it needs that much voltage.
