Hello everyone!

I've done some research but can't seem to get a clear answer.. I have the DeepCool Captain 240ex AIO (https://www.newegg.com/Product/Product.aspx?item=N82E16835856084) and a MSI B350 Tomahawk motherboard (https://www.newegg.com/Product/Product.aspx?Item=N82E16813144028).

I have 6 case fans and 4 sys_fan headers as well as the cpu fan header and pump header. I have 2 fan hubs lying around (https://www.amazon.com/DeepCool-FAN-HUB-Cooler-Powers/dp/B008YD7B0M), so I know I will be able to power all the fans but this is my first time liquid cooling.

I'd greatly appreciate if someone will explain to me which headers I should be using for the aio
Thanks!

PUMP_FAN1 is for the pump.
CPU_FAN1 is for the...


PUMP_FAN1 is for the pump.
CPU_FAN1 is for the CPU fans which are PWM controlled, depending on the temps the RPM will adjust accordingly.
SYS_FAN1~4 is for case fans.

Most people don't plug the pump into CPU_FAN1 because if it fails the mobo will detect it and refuse to boot or throw up an error code upon post.

As for those fan hubs, it depends on how many amps your fans are. Each header can pull up to 1amp. So if your fans were 0.25A, you can have four fans per header.
