First, just wanted to thank DevBiker and everyone else who has contributed to this post - this is great and extremely useful information!
I'm new to the whole PC build thing and decided after years of purchasing pre-fab PCs, that I would build my own (and try to teach my two boys while I was at it). I really liked the Corsair Crystal 460X case and decided to use it for this build. It came with 3 SP120s, and I decided to buy 3 LL120s for the top and back for the case. I knew the SPs didn't natively support fan speed control, so I purchased a Commander Pro to handle that. After wiring everything up and getting the OS installed, I downloaded iCue and was all set to program some RGB goodness, until I realized that I couldn’t mix the LL and SP fans on the same hub. :mad:
Unfortunately, I did not find Zotty's CORSAIR RGB Hardware and iCUE Eco-System FAQ until after I ran into this issue. After reading through his FAQ, I purchased a second RGB Fan LED hub, so I could split the fans between hubs. The other unfortunate thing was that I'd already cabled all of the fans to the original hub, and without re-wiring my whole case, I had no way to extend the RGB cables from my LLs to where I had to locate the new hub. However, while searching these forums, I came across a mention of this post, so I had a solution to my dilemma!
I have a mile's worth of Cat 5 kicking around my house, so I decided to make the extension cables with it. I purchased a wire stripper that could handle 24 awg and a cheap barrel crimping tool for the connectors. I already had a bunch of 550 paracord and a Cat 5 jacket stripper. I purchased the connectors and sockets from Newark.com (no minimum order and cheap shipping) and some heat shrink from Amazon.
I took me a few practice strips and crimps to get it down, but I was able to make 3 16" extension cables fairly quickly. I hooked everything up in my case and voila, I am now able to control the LLs on a separate channel!
Here is my first RGB extension cable:
