I've been using an Asus g-series laptop for two years as my main dj rig. Heavy road use 2-3 nights a week, in and out of the truck, running audio and video and sometimes dmx lighting control. All at the same time. Also use it for audio and video editing. Never once used or even felt like I needed an external cooling source. It is built like a tank, almost as heavy, and takes abuse better than anything this side of a milspec ToughBook. Great choice, and good luck!
