What header to use to hook up CPU fans and cooler on mobo?

CPU cooler: https://pcpartpicker.com/part/nzxt-cpu-cooler-rlkrx6101 On my motherboard there is a header above the CPU that says CPU_OPT and next to that CPU_FAN. I'm assuming that I plug the CPU cooler fans into the CPU_FAN slot. But below those headers there is one that says W_PUMP. Where do I plug my cooler cooler into? The CPU_OPT or W_PUMP?

In normal circumstances i would plug the Pump to the CPU_FAN and the fans to the CPU_OPT header. But this motherboard has a header for the water pump, so you could do it anyway that you want.

You could plug the fans to CPU_FAN and the pump to W_PUMP. It should work fine both ways.. Let me check the manual to see if the W_pump is also PWM.. and ill be back.

EDIT:

page 1-35, all fans headers are real PWM...so it will be fine. Connect the pump to W_pump and fans to CPU_FAN.

If it was a corsair cooler you would have to run the fan header where the pump is connected at full speed..
