Hi everyone,

I am confused on how I should plug the headers of my radiator to the motherboard. I am using ARCTIC Liquid freezer 3 240 A-RGB and an ASUS PRIME X870-P WIFI.

The radiator came with two types of cables:

ALL_IN_ONE: one header with 4 pins with CPU written on and a power cable ( the female with 3 pins).
INDIVIDUAL: 3 cables with 4 pins 'PUMP' 'FAN' and 'VRM'


On my MB I have these options: CPU_FAN, CPU_OPT, AIO_PUMP, CHA_FAN1-2-3-4 and ARGB for the 3 pins one. Which configuration should I use and where should I connect the cables to the MB ?

That one with 3pins (4 but one is missing )is not power but ARGB connector, plug it in appropriate ARGB connector on the MB and control light with SW that comes with your motherboard.
Power cables you can connect in 2 ways, all in one just to CPU_FAN header on the MB and or singles, one from pump to AIO_FAN or any CHA_FAN header on the MB. Both radiator fans into CPU_FAN header on the MB.
 
For most people with that system I recommend using the "All-in-1" cable. The system will control itself well that way if you make the connections as detailed in the manual.

The multi-arm cable set allows YOU to set separate cooling details for the pump, the rad fans and the VRM unit (Voltage Regulator Module) on the pump assembly. This is not easy to do, depending on your own expertise and what abilities your mobo has. Definitely not suitable for new users.
