how come it seems that cooler master is among the expensive ones..
but then from the looks of it doesn't seem to have the ability to really cool the laptop, compared to the cheap ones?

anyway, is this recommended? this is plugged at where the hot air comes out right? does this cooler blows air into the laptop's hot air exit? how does it work?
