Not sure what you are looking at. None of the SBC Pis ever produced, including the 5, will run directly from 12V. They are all 5V input. If you apply 12V directly you will have a dead Pi.To rephrase the original question: Here I plan on using a bigger step down converter. On the page for pi 5's new power supply it show that I could give it 12 volts at around 1 or 2A ish (will check again). The question is then could use the 12V PWM controller with spliced up 12V fans from the same terminals of the converter? Hence the question about units only drawing the current they need or not.
OTOH, you certainly could step down the 45V to feed 5V to the Pi. You likely do not need 3A unless you are doing something very cpu intensive and drawing the maximum power from the USB ports.
