Question Motherboard/ AIO fan/ pump connections..

[wferrante09]

I have a Z690 Aorus Elite AX ATX motherboard and I have an AIO mounted at the top of the case, my motherboard has a sys_fan4_pump for the water cooling pump, should I plug the pump into that or the psu? Also should my radiator fans be plugged into cpu_opt or cpu_fan? This is my first build

Psu: pump runs at 100%, but you lose the option to monitor the rpm via software.
Motherboard header: the pump runs at whatever the curve is preset to. You can customize the curve for that header in bios anyway.
Take your pick, it's nothing serious.

Also should my radiator fans be plugged into cpu_opt or cpu_fan?

CPU_OPT is slave to CPU_FAN; it runs at the same curve(%) as the latter.
Something must be plugged in CPU_FAN first.

This helped me a ton thank you! Where would you put the pump header personally?

Psu, I guess? My input won't be great, as I don't have a preference.
I'm currently using 2 AIOs - the cpu pump is plugged to the psu, and the gpu pump in W_PUMP.
