Help with fan headers

[Man With Computer]

Hello. I need help regarding some fans and PWM mode.

 

My motherboard is a MAG B650M Mortar Wifi.

Then I have a Cooler Master ML240L AIO. The pump has a 3-pin connector. The fans are PWM but come with a Y-splitter.

A Corsair ML140 PWM case fan. I have read that for the bearing to work properly I actually need to connect it to a PWM header. So it wouldn't just be a matter of controlling the speeds.

Some dc case fans.

 

As you can see in the manual, it looks like only 2 of the headers are PWM: the CPU_FAN1 and the PUMP_FAN1. The SYS_FAN1-3 are DC.

Therefore I have been considering connecting the AIO fans to the CPU_FAN1, and then connecting the ML140 to the PUMP_FAN1, which is PWM, and the the actual Pump to a SYS_FAN1. From what I saw in the bios, I would only need to adjust the fan curves or set the PUMP to 100% since the default fan curves for the headers are different. Am I missing something or is this the right procedure here?

 

Thank you very much.

SYS_FAN1 and 2 should be PWM too, if cheaper boards do, more expensive boards would too. 

So pump to the pump_fan1, aio fans to the cpu_fan1, and case fans to sys_fan1/2.
