[SOLVED] Fan Speed shows no RPM ?

Hey all, looking for some advise.

So I am having a few problem with seeing the fan RPM.

Here are some images of the fans that I have connected to the PCB board.

The three wires coming from the fan itself I have connected the three pin and the other connector that has three pins two together and the one alone have been connected to the PCB board that came with the case.

I have the PCB board connected too SYS_FAN1 so if I alter the fan speed it speeds up but it cannot seem to tell me the speed of them.

Here is my system build.

Any advise

4 pin fans are PWM, 3 pin fans don't have the ability to regulate speeds the same way as 4 pin so often bios will see them as 0 even if they are running. I have 3 such fans and the speeds don't show
