Is it safe to say that all 4 pin fan headers (from system to cpu opt)supply 12v each? I can find any detailed specs on my board (Gigabyte Aorus ultra Z390)

Some will offer higher amperage for water pumps, but they're all 12V.

Yup, you can plug 3pin fans into them no issue, the board should detect it as such and still be able to control the speed too.

JD correct any 3 will fit a 4.
Another thing most are max amperage of 1amp so max 10 watt load per fan header on non pump header.
