For anybody who is interested, I have successfully modded some of my Corsair LED fan hubs to work with the Quadro and Splitty4... This has allowed me to plug in 16 Corsair ML fans to just one Quadro and Splitty4... Normally this would need 4 Quadro's and 4 Splitty4's, at significant extra cost and adding heaps more clutter in the case.
Please note, I'm talking about LED control only here, using RGBpx... Fan control is entirely seperate and much simpler.
I plugged in 11 ML fans tonight on a test bench and it all worked perfectly... But should also be fine with up to 16 fans. You can plug in more fans (up to 24) but are limited to 64 LEDs in total.
The mod involves cutting a small trace on the PCB of the corsair LED fan hub and add a short jumper wire. As well as making a 3-pin to 4-pin cable to connect each fan hub to the Splitty4.
I have confirmed that the Corsair addressable LED strips work with the Quadro as well. They simply require a custom cable as well.
Below is a photo of the PCB mod on the Corsair fan hub... Sorry for the crappy lighting, it's late at night here.
PLEASE NOTE... THIS MODDED FAN HUB WILL NO LONGER WORK WITH CORSAIR LIGHTING NODE PRODUCTS... IF YOU TRY THAT IT WILL PROBABLY BLOW UP YOUR FANS!!!! I HAVE USED A PIN THAT IS NORMALLY 5V AND CONNECTED IT TO THE DATA LINES OF THE FANS.
This is brilliant !
I have modified some Corsair hardware myself, and wired generic strips to their ports. I see exactly what you did, All the Corsair LED hubs do is loop the RGB data. Using the hubs (you already paid for) to do the looping, in groups of 6, then pumping it into 1 Corsair RGB port on the Splitty4. So for 16 fans you would need to modify 3 Corsair LED hubs. And then each LED hub plugs into a Corsair RGB port on the Splitty4, which provides +5VDC power and loops the data from port to port. The Corsair LED Hub normally plugs into an RGB port on a Lighting Node Pro or Command Pro. Can you just cut one end of that cable off and attach the 3-pin connector that plugs into a Corsair RGB port on the Splitty4? Those 3 pins being pin 1 - nothing, pin 2 data out, pin 3 data in? If you cut that Corsair 3-pin RGB cable in half, you could make 2 custom cables.
Again, brilliant !
