No, you cannot connect ARGB (Addressable RGB) fans to your motherboard which only has standard RGB sockets menggunakan the Phanteks PH-PWHUB_02 fan controller. ARGB and RGB fans use different connectors and voltages, making it impossible to connect them directly to a standard RGB socket. - ARGB fans use a 3-pin connector and operate at 5 volts, while RGB fans use a 4-pin connector and operate at 12 volts. - The Phanteks PH-PWHUB_02 fan controller is designed to control fans, but does not convert ARGB signals to RGB compatible signals.

Yes... This hub only controls the speed of the fans. For the RGB signals you need a separate RGB hub like this one: Corsair RGB Fan LED Hub

Normally yes, there is everything you need.

I don't remember this detail. I can only say that it works perfectly for PWM, and that the box is correctly supplied with accessories. I think I saw a cable for RGB in there too but that's pretty far back in my memory and I've since sold the PC.
