Recently I purchased a new motherboard for a new CPU, I got the ASUS Prime z370-p and I didn't notice it didn't have LED pins.

I have three front fans that are RGB and they used like a 4 pin LED or RBG input thing or something which my motherboard doesn't have.

Anyway, what I am asking is there like a converter I can buy that would I could plug it into another port, perhaps a USB port on the motherboard? It's not a huge issue I'd just like the extra light in my case.
