Can AP-29 be turned into PWM Fans?

According to this guide:

Seems like it is possible...

I have this:


I have already cut the wire from the female 3-pin and plan to put the yellow wire from the fan into the male 3-pin. So I should have like in the guide two wires going to the PSU and two on the mobo (RPM sensor + PWM).

Wondering if it is going to work before I pull the trigger for 6x AP-29 AKA 75$.

Plus, I doubt 6 fans will fit on the board, what could I do for this? I just need something to duplicate the mobo signal.

You may wish to get a 5-way PWM-splitter. That will allow you to put all the fans on Molex but get their control from the motherboard. With a PWM Y-cable you can add your sixth fan
