One thing about cooling pads, for them to work right the pad fans have to blow in the same direction as the laptop fan(s). If they blow against each other a vacuum will be created thus more heat. Good design would require the CPU and GPU to have separate fans and heatsinks. When overclocking or while intense gaming it would be wise to have the fans running at full speed. If possible use a utility to manually control the fans. I leave my fans running full blast all the time. With continuous use, the heatsinks will collect dust real quick. So shoot some canned air backwards through the coolings vents often.
