I am trying to connect a MSI Coreliquid A15 360 wire connectors to a MAG X870E Tomahawk wifi motherboard. I cannot find any simple diagram or video showing what header (CPU FAN1 or PUMP FAN1) the pump assembly should be connected to. I am trying to use the EZ Conn for the radiator.
 
I originally had the pump wire on PUMP FAN1, but when I booted and went to the bios the motherboard warned that CPU FAN1 had failed. There was nothing plugged into CPU FAN1. I switched the pump head cable to CPU FAN1 and booted again and got no warning. Both the CPU FAN1 and the PUMP FAN1 seem to cool the pumphead, the only obvious difference is the warning about CPU FAN1 failure when nothing is plugged into it. So does it matter which header I use, and if I use the PUMP FAN1 header how do I turn off the warning for the CPU FAN1 header?
