Hello,
I have the same problem right now with my Corsair H110i, it isn't showing up in the 'Temperature' section of the sensorpanel. I thought maybe this could be a similar problem. My file called SiUSBXp.dll is located in this location: "C:\Program Files\Corsair\CORSAIR iCUE 4 Software\SiUSBXp.dll".
Any help is greatly appreciated.
