Z590-E Fan Header

[TheBlahBlah]

Hi,

Looking at the mobo's manual, page 1-9:

C: CHA_FAN1P

😧 AIO_PUMP

E: CHA_FAN2

F: CHA_FAN3

I have 3 Corsair ML120 LED Elite and wanna connect each one to a separate header on mobo, won't use splitters, they are PWM 4 pins with no separate RGB cables.

My question is that may I connect those 3 to CHA_FAN1P , CHA_FAN2 , CHA_FAN3 ?

I mean nothing will connect to AIO_PUMP as CPU has air cooler, so CHA_FAN1P is the same as CHA_FAN2?

What's different about CHA_FAN1P?

Thanks.

Hello TheBlahBlah

Yes, you can connect your three fans to CHA_FAN1P, CHA_FAN2 and CHA_FAN3 headers.

CHA_FAN1P supports ASUS Hydranode fans, but can be used with regular pwm case fans.

Thanks indeed, so CPU fan will go to A: CPU_FAN and the back exhaust fan to the B: CPU_OPT , is that fine?

And in page 1-20 there's a table and the 2 beginning rows are cpu_fan and cpu_opt, the last column is Shared_Control, both mentioned as A, what's that shared control meaning?

Thanks.

You're welcome

You mention you're using an air cooler, does it have only one fan?

The cpu and cpu opt fan headers run at the same rpm. So, when your cpu fan ramps up and down according to temperature, your exhaust fan will ramp up and down too.

It's ok to have it that way, it would help more in exhausting the heat out. You could consider connecting the intake fan to the cpu opt header. This would give a little positive pressure (when it ramps up), this is supposedly better for dust control inside your pc case and you'd be drawing more cool air in.

Either way is ok, you could try it both ways and see which gives better cpu temps.
