This additional pin is used for PWM, but it is not mandatory. Reply to herrwizo m 1 l Best solution i7Baby a c 193 V Motherboard July 6, 2014 2:22:24 AM Use the 4 pins connectors. 3 and 4 pin connectors fit each other. Make sure where Corsair says 4 pin you use the cpu fan header. That's what they assume is 4 pin. usually the case (or radiator) fans were 3 pin. Its now more common to see 4 pin connectors everywhere. Reply to i7Baby Share Can't find your answer ? Ask !
