Question best fan and aio connection?

[AndGarP7]

hello everyone,

i have a problem with my system:

MB: asus rog x870e hero
cpu: amd 9800x3d
aio: asus rog ryujin iii extreme
fans on aio radiator: x3 a12-25 pwm noctua (top exit)
rear fan: a14 pwm noctua (rear exit)
front fans: supplied with hyperior case (front entry)

I can't read the fan speed on front fans, also I'm not sure if I connected everything in the right place

connections:
- pump: aio_pump
- front fans: fan 2, fan 3, fan 4 on hyperior supplied hub
- rear fan: cha_fan4 on motherboard
- fans on radiator: cpu_fan, through a 3-1 splitter (4-pin male, one 4-pin female and the other two 3 PIN)

the hub (mb pwm) is connected to the mb (cha_fan1)

in fact in the bios I am able to view/set everything, but:

-fans on radiator on cpu_fan
-rear fan on cha_fan4
-pump on aio_pump
- the front fans are working and I can adjust the speed, but the speed is not read (Fan speed N/A)

P.s the aio screen always shows 10 degrees less than hwmonitor

What would be the right wiring?

Thanks

hyperior supplied hub
If you're seeing RPM for one fan, that's due to the fan hub. A hub will never show you the RPM for all the fans hooked up to the hub, except for the first one. To note, I'd advise hooking up the fans starting from 1 and work your way up. Hook the hub up to CPU_OPT and see if you're BIOS can read the RPM.

thanks for the reply,

well, it doesn't actually read the speed of any of the three fans, I'll try your advice..

is everything else connected in the right positions?

It might be easier to ditch the hub for at least fan control and use another 3 to 1 splitter to connect the fans to another chassis fan connector. There are also argb splitters up to 5 to 1 which might help eliminate the hub entirely. I also prefer HWiNFO for monitoring everything.
