H100i Elite Capellix not detected anywhere


Recommended Posts

So I have a Corsair H100i Elite Capellix. It worked fine for a while, aside from the motherboard complaining about a CPU Fan Error even though the Tach cable was properly connected to the CPU_FAN header. I just ignored this issue though, as otherwise the unit was fully functional. Worked upon startup, fully controllable in iCue. There were a few times where the RGB block wouldn't be recognized for a little bit after I disconnected it while in use, but that would fix itself.

 

At least for a while. At some point, I disconnected it once again while in use accidentally while trying to swap the face plate. It once again wasn't detected after being disconnected and reconnected while in use, but I figured it would resolve itself like the times before. But it didn't. But everything else was fully functional, I just couldn't control the RGB block anymore. And then the next day, the Commander Core also wasn't recognized. Fans weren't spinning. The pump wasn't running.

 

At that point, I had to effectively jump-start the unit by disconnecting and reconnecting SATA power. As a result of this, everything connected to the Commander Core would run at full speed, no matter what the temps were.

 

I tried all the normal steps, fully uninstalling all Corsair software, uninstalling Aura Sync, reinstalling iCue, but to no avail. The unit wasn't detected. It wouldn't start up with my system- I had to jump-start it. I looked for another solution, which led me to the "Bluetooth and other devices" panel of Windows. The unit is supposed to show up there, but it didn't.

 

I powered off the system once again, and reseated *every* connection multiple times. This also didn't help at all. I still can't control anything, and the RGB is still either forced to my hardware profile (RGB OFF) or just doesn't work. I don't know which.

 

I then decide to look at Device Manager. I see the Corsair USBxp driver, and decide to uninstall it. Maybe it was corrupted somehow. I uninstall everything Corsair once again, and reinstall iCue. Still nothing. Not detected anywhere. Unit still doesn't start up with my system. Not even with a fresh OS or in the BIOS. Just doesn't work without jump starting it.

 

I suspect it's an issue with the Commander Core, and as I can't afford to RMA as I don't have a replacement cooler on hand and need my PC daily, I plan to just buy a replacement Commander Core. However, they haven't been in stock so I haven't been able to do so.

 

However, if anyone has any other suggestions, PLEASE. For now I've opted to have the fans connected to my motherboard and that sort of works, but it's not ideal. I shouldn't have to do this.

 

EDIT: Also tried: Different PSU header, Different SATA power plug, the other USB 2.0 header, different fan headers for the pump tach cable.
