Weird Issue with Marquee Effect/LED detection

Hi all. I am having a weird issue using the marquee effect and getting my fans to all be detected as the same light configuration. I am making a Fallout: New Vegas profile that has an orange background with yellow marquee effect to be like a roulette wheel/casino marquee. I have 6 ML120 Pro RGB on my Commander Core, with two separate ML120s on a Hub connected to a Commander Pro. For some reason, some of my fans are not doing a nice alternating marquee pattern, and are acting like there are only 4 "dots" on the fan. The marquee does a weird "quarter, quarter, half" pattern.

 

To add to the weirdness, 3 of the 6 on the CoCo are doing it, as well as the 2 on the hub. The other three are not. The three on the CoCo are displaying like they have more than 4 lights, but are not acting like they actually have those lights. The ones of the hub won't even display in iCUE as having more than 4 lights. At first I thought it was the ones I had recently purchased and the LEDs were installed wrong, but the 2 misbehaving ones on the hub are from my original build.

 

The CoCo gives me the option to auto-detect, which works for getting the nicer effect for half of the fans. The hub/CoPRO doesn't give me the auto-detect option, and selecting ML120 makes them only have 4 detected "dots". I know it is possible to have more light options because some of them act as expected, but some randomly do not even though they are connected to the same controller.

 

Is the auto-detect on the CoCo doing something incorrectly to make the ML120s do things they are not intended to do, but not extending to RGB ports 4-6 somehow? I'd hate to only be able to have 4 "dots" to play with.

 

I hope I have explained this correctly, and I'm happy to clarify.

 

TIA.

Since you have a commander Core, I will assume there is an Elite cooler and its fans some where in the system. That is the basis of the issue. The ML-Elite that come with the cooler have 8 center hub LEDs (like a SP-Pro) and the ML-RGB that have been sold at retail for the past several years are 4 center hub LEDs. The Commander Core will take the fan with the highest LED count and use that as the base for the UI and programming, despite the physical differences. This can lead to odd effects or incompatible results, like a center LED hub fan trying to do ring effects without an outer ring.

 

Only the Commander Core does the auto-detect, but it’s not capable of running multiple fan types as different fans. On the other controllers, you must designate the fan type and number (ML-RGB x 6).

 

The only immediate solution I can offer is to put all your 4 LED ML on one of the controller and the ML-Elite 8 on the other. Doesn’t matter which and PWM control is completely unrelated. They can be speed controlled on the Com Core and lighting controller on a different controller, but it looks like you have enough hardware to do this. Fair warning — marquee is not as attractive on the 4 LED fans.

Thanks! I knew it had to be something weird like this. After looking at my bottom front fan more closely, it is indeed one of the 4 light fans doing the terrible marquee effect while the two above it look great, so that jives with what you are saying.

 

Sure would be nice if Corsair had made that distinction more clear than "2 ML 120 fans" in the specs for the AIO kit fans or made it possible to buy more fans that actually match it. What is the point of including a CoCo that can't run more than one type of fan if you can't actually buy more fans to put on it that match?

 

Seems like I am getting lucky using different fans on the CoCo and treating them all as the 8 LED model. Because 4 is half of 8, I'm guessing it is just pairing up the lights. Unless I run into issues, I will probably just leave the cables as is.

 

Now to figure out why software control doesn't work on my RAM unless I reinstall the firmware on every boot...
