even if you manage to, to a certain degree. the heat and power consumption would (to me) not worth it.
i mean, all laptops that i have tried, playing games on them, they heat really heat up.
think of it this way, when people oc the cpu on desktops, they buy third parth cooler because the stock cooler is not good enough for that. now that stock cooler is (i am guessing) bigger than what laptops have. if that is inadequate, then more so for the laptop cooler
