Common people you dont need that info... 3 pin connectors can safely be used on 4 pin headers by aligning pin 1 with pin 1 on the motherboard connector pin 4 will be ignored.
Pin 4 is for controlling the speed of the fans. Thus is fans are not speed controllable...
they said both the fan connectors and the motherboard connectors are male
how exactly did you plan to plug a male connector to another male connector?
and no rude answers please
