I'm so sorry, again I'm a rookie builder so it's hard to grasp this. So just to get this straight.
1. The X73 will have a core hub with 3 connections that will let me power 3 LL fans.
2. The RGB hub that comes in the 3-pack of LL lights can be used to control the RGB of 6 fans BUT, if I have 2 RGB hubs, can I daisy chain them so the RGB wiring from all 9 fans can be connected to the 2 RGB hubs?
3. If I can do #2, how would I power the RGB hubs?
