This looks nice and might be fine for regular laptops, but usually coolers with one central fan don't deliver enough airflow in the right locations for gaming laptops. I personally use a Cooler Master Notepal U3, which has 3 smaller fans that can be placed in any desired location under the laptop. But even then I've only noticed minimal effects on the GPU temps, a little more on the CPU temps, but it did actually cool the hard drive quite a bit during intense gaming (~5-7°C lower). I think the best solution is to use compressed air to dust out the laptop and exhaust fins every few months (for me, that made the biggest difference). Most gaming laptops are designed with pretty good air flow and heat dissipation by default.
