X570 Steel Legend CPU_FAN1/2 broken

   There seems to be a bug with how the motherboard handles CPU_FAN1 and CPU_FAN2.

I can plug in a 4-pin fan to either by itself, and it works just fine.
I can plug in a 3-pin fan to either by itself, and it works just fine.

However, if I plug in a 3-pin fan and a 4-pin fan at the same time to CPU_FAN1 and CPU_FAN2, regardless of which one is which, the 3-pin fan spins but the 4-pin fan will not spin at all--no setting in the motherboard will change it.
