Hi all,
Had to format my PC, so a fresh updated install of windows.
Installed latest iCue (3.9.93).
As soon as I loaded my custom fan profile, the freeze happens eventually.
I'm convinced that if I load one of the default profiles (Quiet or Balanced for example) this issue doesn't occur.
I also used HWInfo to see if the problem was with iCue getting readings, but the readings there also failed.
