Thanks for the help, I have got no where with solving my iCue control issue with support. So I have done as you have suggested, but want to ask a couple of things due to my lack of experience. Which will likely help anyone else that finds this thread. It appears to work great controlling the fan with the mixed CPU/GPU temp.
There are two fan inputs at the top of the mobo, Fan1 already has a single wire cable coming out going somewhere, and the other (fan2) empty.
The cable for the main fan cannot reach the open slot, so I have moved the single wire cable to Fan2, and plugged the main top fan into Fan1 slot.
Then simply installed FanControl, which I agree is amazing.
First question, do you know what that first original fan1 wire was for?
Are the watercooled units independent, i.e there is no need to try and control anything re RPM for those. They don't seem to really appear on my FanControl.
Are you still able to control the RGB on the box?
