I was looking for information about combining multiple fans in a 48cm radiator setup. The fan I plan to use is the Noctua NF-P12 Redux-1700 PWM. The specs say it should handle up to 1.08W input power, 0.09A current, and 12V operation. I’m wondering if I can fit around four of these fans in a single header on my Z390 Master. I was considering using just three at a time, but I’m curious about the typical amperage requirements. I also have a few other Noctua models—three 140mm and one 120mmx15mm fan—and I wanted to clarify if the header supports up to 2A total. Thanks for helping me sort this out!

It's typical. On average, a fan uses about 0.18A. My Noctuas ran around 0.30A or similar, which is nearly double at 3000 RPM. You should be fine. I recommend not exceeding 1A per connector.
