My single Commander which came with my H150i Elite Capelix cooler isn't detected.

The unit is no longer under warranty so if it's a hardware issue I'd have to keep on using a PWM splitter until the unit dies completely. Seems all Corsair items I buy have a lifetime of 1-2 years ...

To clarify, if I swap the fans the #2 logical fan is still the one running at full speed. So it's not a faulty fan. Something is either wrong with iCUE or the AIO fan control port is somehow broken. I have seen a number of other users here pointing out similar issues so suspecting it's iCUE.

How?

It's not the fan. Swapping the two fans makes no difference. I also forced a firmware update and it made no difference.

The first fan is controllable and changes speed if I change settings for it, the second is running at max no matter what. If I swap the actual fans nothing changes, the same fan ID is running at full speed, so it's not the fans. Looks like a bug.

Perhaps that could be supported on the Commander Core XT as well? Seems like a great feature.

This disappeared and now it's back again. Driving me nuts.

a) It's connected via a powered NZXT USB HUB. b) Only MSI afterburner but that's only controlling GPU fans.

I have 4 fans connected to my Commander Pro. All fans are spinning. I have 4 light strips connected as well and they are on and change colors correctly. However in the iCue setup view they all come and go. They show for a few seconds and then disappear.

I would recommend you make better software. I have the same issue, again .... @LightweightSoft Try this: https://help.corsair.com/hc/en-us/articles/360025166712-Perform-a-clean-reinstallation-of-the-Corsair-Utility-Engine-iCUE-

And now ICue has managed to uninstall itself. The program is running (hanging) and the files are gone. And installing it again doesn't work so now I have to manually clean up again. Jesus what a pile of rubbish this is.

This is sad. I installed the latest version 4 update because it popped up. And then what I have starting up is version 3.38.61. So I downloaded 4.10.273 and installed it. And it still starts version 3.38.61.

Installed and working. Upgraded from a clean 3.38.61 install with minimal profiles. No issues so far.

Lol, sure. Did that a couple of months ago and didn't hear a peep.
