Question about be quiet! Pure Rock 2 FX

argb (addressable rgb) is simply how the rgb's work. It only requires the 4-PIN PWM connector on your particular motherboard. To see if your motherboard has the connector, you can look in the manual or find it yourself if you know what to look for.
You don't even need the bequiet software for the rgb's to work, but you do need it to switch to other lighting effects.

I hope I could help and I wish you good luck with your purchase decision
