and what about turning off and on the cooling? What about writing script
to automatically turn on and off the cooling when is needed or some
script to turn on and off the cooling by key binding or command? Is it
possible? I have Monitor toggle script to turn off and on the screen. Is
it possible to do with cooling?
Thanks a lot.
