to the right we have 4 pins cords (watercooling fans)
to the left we have 1x 4pin cord that goes from the watercooler
and we have 1x 3pin cord that also goes from the same cord as the 4pin from the watercooler..
and then we have this 3 pin connector that also comes from the water cooler...

I can't find a 3pin connector on my motherboard and I'm pretty sure the 2x 4pins for fans should go in a similar connector... why is there a 4pin and a 3pin connector ?
