Fans that do use 3-wire connectors can report their speed. They are also called PWM (Pulse Width Modulation) and require compatible control from motherboard and it's BIOS and not all the 4 pin MB connectors are true PWM. The DC voltage is converted to a square-wave signal, alternating between fully on (nearly 12V) and zero, giving the motor a series of power "kicks". The third type of fans that use four wires are PWM fans and that is what PWM (Pulse Width Modulation) or modulation with the width of an Pulse-Width Modulation.
