Cooler Master Addressable RGB Fan Controller

[scojer]

My mobo has the older 4 pin RGB connectors, and I just bought some coolermaster fans. They're 3 pin connectors, and they came with a default controller that does red, green, blue, or rainbow.

I found this: https://www.amazon.com/gp/product/B07H241TFT/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1

Anyone have experience with it?
It looks like I can connect it to internal USB, or the 4 pin connector.

Just wanting some opinions before I pull the trigger!

Thanks.
