Always good to get those clean once in a while. (I may be on a summer fan-kick though - I took apart both house-fans we use here to clean their blades and the motor-area on the one I could get into easily... both are more efficient, and somewhat faster now) .
Once a year, I bring my system down to the garage and used compressed air to get all the dust out. Do it outside, because the amount of crap in there is disgusting. Same with the keyboard.
