'Intelligent Cooling', pfft. Marketing mumbo-jumbo that doesn't mean jack... but if it's drawing in customers, then props to Asus' marketing team, because it's working as intended.
A cooling pad isn't even necessary. All you need to do is raise the back end of the laptop. This will improve ventilation.
No real need to throw 20-30USD on some fancy cooling pad - which, by the way, it's the elevation that's contributing the most to the enhanced cooling, and not the fans than some manufacturers slap on 'em.
