So far I have updated the firmware, and stopped the "always on at full" situation. The problem that remains is that the Corsair Link software doesn't recognize the H100i unless I unplug it from the motherboard and plug it back in a different USB slot. It doesn't matter which slot its in when I boot, so far this repluging is required every time I want to use Corsair Link.
Ugh! Anyway, is there a Bios setting or something I can do to stop having to do this?
I have the H100i, with a Asus Z87 Pro motherboard.
