Check the specifications for the Z390 Aorus Master to confirm the maximum amperage rating of all fan connectors.

You currently have a setup with several fans drawing different currents. Adding two ML120 Pros at 0.225A each would increase the load to about 2.95A. Check your motherboard’s power connector capacity—most modern boards can handle up to 5A, but ensure the PSU can supply it. Connecting them directly to the motherboard is usually safe if the board supports it, though you may need a proper power distribution setup.
Typically the fan headers provide at least one amp each, which means the overall capacity comes to about 8A. If you streamline the fan connectors, it should work fine.
Refers to adjusting settings for better performance, but the manual doesn’t explain it clearly.
Avoid connecting every fan to one main header. Limit each header to 2–3 fans, though two fans per header are possible.
This has been the usual approach for a while now, which means it makes sense for such an expensive motherboard.
The SYS_FAN models 1 to 4 operate at 1 amp, while the SYS_FAN_PUMP versions 5 to 6 require 2 amps each. Everything should work fine.
I didn't realize I needed to check the current draw for the additional pump, but I think a splitter could help manage both speeds together.
Gigabyte responded and confirmed 1A per header. Everything looks good. EKWB provided an update on the pump, and I can use both PWM connectors on a single header with a splitter—it's only for speed signals and draws minimal current.
