Thank you for your response. This was the kind of information I was looking for. Do you think it would be easy to find the PWM frequencies myself? Do you know if there are any datasheets I can use to build my own hub?

You're in luck, since the server is written in Java, we can install it on ARM based devices, including the Pi. Just follow this tutorial.

My problem I have 3 RGB fans in my case (Corsair Carbide SPEC-DELTA). But no RGB header on my motherboard. How can I control these in the cheapest way possible? What I did I bought an Corsair Commander PRO for almost the price of the whole case. But I can't control the fans because the fan RGB header can't be plugged into the controller. I RMA'd this stupidly high priced product and hoped you can help me fixing this. It seems like there's a standard for the RGB connectors. This is the the RGB connector my fans have: Since I could plug this into any motherboard (with a male to female converter) and control it with any software, I should also be able to use any controller. But from what I've read, different vendors use different protocols. What I think is the case There is one intercompatible RGB standard, using the connector seen above. With which you can do basic RGB control. Each vendor also has it's own standard with different connectors, with which you can do more in-depth control and address leds in a fan individually. If this is the case, can someone recommend me a controller? It doesn't even need to have fan control. It just needs to be able to address these fans. Thank you.
