So if a fan has a 3 pin wire and a molex. do both have to be plugged in or could you just get away with connecting the molex without plugging 3 pin in?
Does the 3-pin connector have only one wire? If so that is made to connect to a motherboard header so it can sense a CPU cooler fan is connected. A safety feature.
