it makes a huge difference !
it is like this - if i am listening to music, and also working on the laptop (for Hifivision) then the fan is on.
but, if i am listening to nusrath fateh ali khan, especially the 2nd track on "NIGHT SONG", the fans go off!
@ murali - those high end dealers know what they are doing!
true..also the regulator for the fan especially if it is the small rotary type actually ruins the power...so even if you run it, it better be on a separate line !
