I'm having a very similar issue and I also have a Msi motherboard. I've even returned the original one and recieved another. However I'm still having the same issue the pump,fans and fans LEDs work but not the led for the pump. Any solutions?
I'm having the exact same issue, I just installed the other day everything is connected properly and the LED on both fans work its just the pump.
