So, I have a question about the fan and pump PWM control. The plan is to do the following. I will use two DDC pumps with a SATA connector and 4 PIN headers (PWM Control). These pumps (20 watts each) will receive power from the PSU two-SATA connectors.

Options 1 - Connection Configurations
CPU_FAN - Daisy chain three-Noctua NF-A12x25 PWM fans (top of the case).
CHA_FAN - Daisy chain three-Noctua NF-A12x25 PWM fans (top of the case).
AIO_Pump - Daisy chain, two DDC Pumps are used for PWM speed control of the pumps.
I will use Fan Control to run the system.
Since I am using the PSU to power the dual pumps, hooking up dual PWM control to this single AIO_Pump will be ok. I am not sure.

Options 2 - Connection Configurations

The other option is to use a single-Aquacomputer – QUADRO fan controller for PWM fans, and all inputs have 25 watts of power. This option can remove the need to connect the dual dcc pumps to the PSU.

Fan 1 - Daisy chain three-Noctua NF-A12x25 PWM fans (top of the case).
Fan 2 - Daisy chain three-Noctua NF-A12x25 PWM fans (Bottom of the case).
Fan 3 - DDC Pump
Fan 4 - DDC Pump
I will then have to use Aquacomputer software to run the fan's PWM software.

Both options will get their power from the PSU.

I like the option of using the motherboard; I do not have to use another device to make this work. Mentally, Daisy changing two PWM controllers to a single header should not be an issue. Since the power comes from the PSU, I think this will result in lower power consumption.

I have the same motherboard with 9800x3d but less cooling Asus ROG RYUO 240 ARGB it cools the system great even at 5.5ghz. Back to your question I would use option 1 if you have a big power supply. I like using the Fan control on the motherboard.

Thank you so much.
And I should not have any issues with Daisy chaining the PWM controls for the pumps.
I like option one, so I do not have to have another accessory to run, and the PSU can handle the power.

Thank you
