NZXT I don't say anything else.
The software needs some work, to set your own mode you need to set each LED individually in the software.
It has double-sided adhesive stickers to stick them.
Be careful, these come in 2 sizes. This one is for a large case, there is also a small one.
Don't make the mistake of getting the large one, they won't fit underneath.
Also, if you exceed the limit of the LEDs continuously, like I did with the fun RGB and additional NZXT LED strips, they won't light up, even if the software reads them, it will show white cubes in the program, and they won't be able to light up simultaneously.
You will need a second NZXT RGB Fan Controller.
Fantastic for the money.
