If it's older CM AiO, connect pump to w_Pump connector and make sure it's set to full speed.Hello, I have a gigabyte gaming 7 Z370 motherboard. Also I have a cooler master 240mm aio. Right now I have my pump plugged into the CPU_OPT. I have the fans connected onto the radiator plugged into the CPU_FAN header. Is this the right configuration.
