Hello, I'm having the exact same problem as below. Has there been any solution. This is very disapointing. I have all Corsair gear and I bought this H115 just to match everything else.
Bought a brand new h115i Platinum a week ago. Installed, it booted, RGB working. Showed in iCUE. There was a Firmware update. The firmware update failed over and over again. I decided to stop trying the update.
I reboot my computer.
All RGB is off, iCUE does not recognize H115i Platinum.
