Comes with coolermaster LED controller A1 which is around $29 separately. This not the tiny one you see in the old reviews. Controller does not control fan speed. Pack comes with the fan splitter cable for speed.
The fans and controller are ARGB gen 2.
This means you can daisy chain RGB GEN 2 fans to each controller header and still control them separately.
Unfortunately each fan has 30 LEDs and each of the 3 controller ports can handle 80 LEDs so you can only daisy chain 2 of these fans to one of the controller headers. Still plenty of room to add things, as it connects to motherboard usb header and SATA power.
I never was one for bling, I'll probably just leave them white, but they are honestly nice. White looks great. The cooler master software does the job, you can control each LED separately which was enough for me.
Lol. Check out the review. Grace put 24 of these in their case.
Pros: Look nice
Cons: Draw too much power.
