My motherboard doesnt have enough 3 pin adapters or the fans cannot reach them. Just installed my watercooling - all is well apart from i can only have 2 fans/3 on rad working, 1 out of 3 exhaust and 1 out of 2 intake (side). Do i need those 3 pin/molex connectors? What are they called and how cheap can i get them for?
