I realised after using the older command center for a while that the lights are fine but the fans (witch is worst) go full speed under very light stress.
I called alienware support and even if the 8.1 driver is out in the Dell site they insist that they do not support 8.1 and tells me to re-install windows 8 , I saw a possible fix but it seems very complicated so I did not do it.
I am still wondering what I should do, wait for the 8.1 support or start anew with windows 8 , but I am convinced that command center will not work properly after installation of win 8 but at least I will get support.
