LL120 fans have 4 pin connector, my MOBO has 3 pin (not PWM)

Trying to install my LL120 fans. My old NZXT fans that came with the case are only 3 pin connectors, as well as where they connect on the motherboard. I understand that you can install a PWM 4-pin into a 3-pin and it will just run at full speed.

 

But is that 4th pin also required for the RGB to work? I have everything installed, but no lights come on and iCue is not detecting anything. I double checked all of the connections and everything seems right. Do I need some sort of adapter? Thanks for any help.

Not entirely accurate. Some PWM fans can be controlled using voltage control (3-pin). I believe this will work with the LL fans.

 

As for the RGB - see the RGB FAQ.
