The Commander Pro is not required. You can also control the fans via fan headers on the mainboard. The settings for this can be found in the Bios. If there are not enough connections on the mainboard, you can also use a Y-cable.
You can connect two fans to one fan connection via a Y-cable. Otherwise, use a fan controller and then connect it directly to the power supply. RGB is controlled via the Corsair Hub!
Hello, yes it should be possible. However, if it's an older watercooling system that only manages the speed of the fans, it won't be able to manage the coloured leds. It will be necessary to use the controller supplied with it for the led and the one for the fan to manage the speed.
Hello, Mike.brisacher. What do you want to light up? The parts in the picture can also be bought separately. Write what you have and what you want to illuminate, maybe we can find a solution for your problem. Kind regards
