To remind those in the market for a gaming laptop, Asus didn?t approach this design with shrinking violets in mind. Rather than slimming down the design, the Asus ROG G703 ?beefs up to 51 mm thick to make room for an elaborate cooling system? to ensure it performs under pressure. Portable gamers please bear in mind that it weighs in at 4.8kg and packs an eight-cell 71Wh battery.

With the release upon us Asus has provided more detail about technical aspects of this laptop such as the cooling. We hear that the new G703 uses a ?patented Anti-Dust Cooling (ADC) system? which facilitates the i7 to be overclocked to 4.3GHz, and the GPU to be overclocked to 1974MHz. The ADC keeps dust out, as you might expect from the name, and the offending particles are ejected through two dedicated tunnels. Elsewhere, the cooling system relies upon an arrangement of 12V cooling fans and heatpipes.
