The description isn't that clear and if you're new to custom water cooling and rgb lighting it may be difficult to know if this would work for you.

So my motherboard only has a 12v rgb header. I bought a Bykski rgb cpu water block, rgb reservoir pump combo and 14mm hard tube rgb fittings. They are 5v rgb. Plugging those components directly into one of the LED connections on the light controller module allows you to control them via remote so you can by pass your motherboard rgb controller.

Also when you boot the system it starts on whatever color or program you selected last. You can have your pc light up in green only or rgb. I believe you can also program it which I haven't done yet.
