[SOLVED] Pump and fans to which header

[Kruppster]

I have a Asus Rog Strix x570-I gaming motherboard.

I am building a system with:

DC5 water pump
2 radiators with 2 fans each (the fans are Noctua PWM fans)
1 or 2 chassis fans (Dumb fans?)

My dilemma is, which headers go where on the motherboard? The manual states the following:

"Connect the fan of your water-cooling kit to the AIO_PUMP connector"

and lists the headers:

CPU_FAN

Header	Max. Current	Max. Power	Default Speed	Shared control
CPU_FAN	1A	12W	Q-Fan Controlled	-​
CHA_FAN	1A	12W	Q-Fan Controlled	-​
AIO_PUMP	1A	12W	Full-Speed	-​

But do I want to have my pump running at full speed?

What is the way to go in my situation. Your help is much appreciated.

If not seriously overpowered, pumps are generally "happy" to run at full speed. That also assures lower idle and mid range temps. Always recommended for AIO coolers. If you connect pump to adjustable speed connector like CHA_FAN you have to make sure that it's tied up to CPU temperatures or it may not have adequate speed.
So, I would (and usually do) connect pump to AIO header.
Don't know what you mean by "Dumb fans", most are just 3 pin or 4 pin (PWM) and speed can be controlled thru MB and BIOS settings.
PS:
Make sure you have balanced air flow, too much of either or exhaust can be not so good. If you make one radiator as intake and other as exhaust, you may not need any case fans if it's all in a small case.
