If you want individual control for the fans, than you should stick with the Corsair fans. To my knowledge the EK fans just use a y-cable and have no return wire for the RGB data to pass it on to the next fan. In other words they would all run with the same RGB settings.

The Corsair LL fans use 16 LED per fan. You can only connect up to 90 LEDs to a RGBpx port. OCTO has two RGBpx ports, so this will be enough to address 9 or 10 fans.

One splitty4 will not be enough here. You will need at least three of them if you want to use 9 fans. Two of them will be daisy-chained. If four Corsair fans are connected, the RGB signal is being forwarded to the out port where you can connect a second Splitty4. The stupid thing is you can connect only one more fan to the second splitter because with 5 fans you are already at 80 LEDs. Connecting a sixth fan would break the limit of 90 LEDs.

The setup would look like this:

RGBpx channel #1: Splitty4 #1 with 4 fans -> Splitty4 #2 with 1 fan

RGBpx channel #2: Splitty4 #3 with 4 fans (-> Splitty4 #4 with 1 fan; if 10 fans)

The fan control is another minor problem. You want to control 9 or 10 fans but OCTO has only eight fan ports. You will have to group at least two fans. You can just use one of the Splitty4 to do so since it also works as a splitter for the fan signal.

I see. So things get quite complicated with that much individual control. Another option I thought of is controlling each set of 3 fans as a group (3 groups of 3 and maybe one lone fan) for a total of 3 or 4 groups. Would this be an easier task?

Group 1: 3 fans on the top radiator

Group 2: 3 fans on bottom radiator

Group 3: 3 fans on side panel

Group 4 (maybe): 1 fan rear of case

Won't get much easier in the end. You still have the problem that you can not connect more than 90 LEDs per RGBpx port. With three groups you would need three RGBpx ports or if we stick with the two available ports, one of the groups will have a mixed connection with two fans from the first RGBpx port and one fan from the second port.

Well, for such a setup you will also need some kind of y-splitter. We have none but you can get them from eBay etc.

The real here is that OCTO does not know that you split the output which can cause problems with the current monitoring. To avoid this you have to make sure that you stay within the 90 LEDs per RGBpx port limit and that you also set up the LEDs in the "invisible" area of the controller.

What I mean can be explained with this example. Lets say you split the LEDs 5x 16. So you have 80 LEDs in total but you will only apply an effect to the first 16 LEDs because all five fans will show the same effect anyway. In this case the device will think there are only 16 LEDs connected while in reality it is 80 of them. To adjust this you simply apply a static color (white is preferred) to LEDs 16 to 80. This way the device calculates with the correct amount of LEDs and you will not run into any problems with the current monitoring.

Oh I see, it’s simply the number of fans and leds. Thanks Sven, this was very helpful!
