How do I connect the case fan to the MB? It is a 4 pin to a 3 pin. (case fan cable is 3 pin, MB is 4 pin). Anyway, my MB is Z97-E usb 3.1. I understand that you should connect the 3 pins to the right of the 4 pins, but it does not fit well. I have pictures. Googling, I found out that you connect the wires to the side case fan wire, then connect the molex somewhere.
3pins to MB 4pins
Then, I found that I might have to connect the side fan to the earlier 3 pin, and it fits and clicks! But then, I do not know what to do from there. I heard I have to connect this molex cable to something, but I do not know what. My PSU is the Corsair CX650M. Thanks in advance for advice!
 
Solution
connect this molex cable to something--------that is one style connecter for cd drives and hard drives. you might not need to use it if they took the flatter type power cables.
