Process Posted May 6, 2021 Share Posted May 6, 2021 (edited) Ok, so cliff notes: Commander Core RGB Slot 6 is faulty with three different commander core units and have tried it with over 10 different Corsair RGB fans. The story: I got a Corsair H150i Elite Capellix as a gift in December 2020. I installed it in my case, and hooked up the three fans that came with it to the radiator, as well as 2x LL140's and 1x LL 120 for my case exhaust fans. It worked perfectly fine until April 2021. The RGB on Fan #6 (the rear exhaust LL120) would flicker, and then eventually go out. So, I swapped fans, nothing. I moved the fan to another RGB slot on the commander core, and it lit up. I did this through various other corsair RGB fans I had laying around, same issue. I didn't have a receipt for it, since it was a gift, and corsair wouldn't RMA me a new commander core initially, so I decided I'd just re-purpose the cooler for a different build and go buy another unit. Wouldn't you know it, Commander Core #2, also wouldn't work in RGB Port #6, did the same trouble shooting. I immediately returned the second H150i Elite Capellix, and got another one. Guess what... RGB Port #6 also doesn't work on commander core #3. I was also at the time building a new AMD 5950x system, so I moved this water cooler over to that system... same result. So now, 3 different commander cores and 2 different systems, and 10 different corsair RGB fans, RGB port #6 does not work, running latest versions of iCue, and forcing firmware updates etc. Corsair finally decided to send me another commander core for me to try after being on the phone with them for an hour. What gives, am I just unlucky or am I perhaps missing something?

Corsair Employees Corsair Notepad Posted May 6, 2021 Corsair Employees Share Posted May 6, 2021 Mixing different RGB Series fans on the same controller is a no go. The fans that come with your cooler have 8 RGB LEDs where the LL Series fans have more and the iCUE software controls fans based on LED counts. You will need to utilize a completely different controller/hub setup for the LL Series fans. Please refer to Zotty's pinned post at the top of the iCUE Sub Forum for my in-depth explanation of our RGB ecosystem and how things connect and are controlled via the iCUE software.

Corsair tech support line says otherwise, as there was a firmware release in January 2021 that allows all Corsair RGB fans to work on the commander core, they state it is no problem using a commander core with the supplied fans and LL fans. Perhaps you need to a little more up to date with corsair offerings? It also worked perfectly fine for 5 months, and is still working fine for the other 2 LL fans on the commander core in slots 4 and 5. Your response is not an explanation for the issue. Also I've plugged in the included fans that came with the H150i Elite Cappelix into RGB port 6 on both brand new commander core units and both were duds out of the box? Whats your explanation?

I am sorry to inform you but whoever you spoke with was mistaken as there has been no firmware push for the Commander Core that allows you to mix different RGB Series fans on the same controller. Mixing RGB fans no matter what controller you have is a no go right now. They may light up and look like they are working but due to the different RGB LED counts per fan the effects are not going to work correctly and you indeed will run into the issue you are experiencing due to this.

Process Posted May 6, 2021 Author Share Posted May 6, 2021 then why do the fans that "do" work with it are not working on port 6 for three different units brand new out of the box? Link to comment Share on other sites More sharing options...
Corsair Employees Corsair Notepad Posted May 6, 2021 Corsair Employees Share Posted May 6, 2021 The RGB ports on the Commander Core work in series just like our Lighting Node Core, and the RGB Fan LED Hub. In the iCUE software you tell the software how many fans are connected and the exact series of fans. From there the iCUE software is set to control a set amount of fans based on the LED counts. So if you have it set to the the 8-LED Count fans x6 that is only 48 LEDs the iCUE software will attempt to power and control. By mixing in LL series fans with the 8 LED ML Elite fans that come with the Capellix cooler you will reach that 48 LED limit before it reaches the final RGB Port. If you skip ports in an attempt to test only Port 6 on the Commander Pro you are breaking the series and therefore no power or signal is reaching Port 6.

Process Posted May 6, 2021 Author Share Posted May 6, 2021 icue settings were never changed, all fans initially worked. Even if just 1 fan is plugged into port 6, it won't work. On 3 different units Link to comment Share on other sites More sharing options...
