Noob here I have got the thermaltake 360mm ultimate but idk where to plug in the pump to the motherboard I’m using a MSI MPG Z390 Gaming Edge and all the sys fan are 4pin and I don’t see anything with a 3pin like this cooler is needing. So where would I plug this in at? I got the three fans on the radiator plugged into the cpu_fan like the Manuel says to do but the pump is confusing me.
