toshsatproa300heatsink

the heat sink of the toshiba satellite pro a300. now i used a very small dab of heatsink paste. there was a pad before. and i think it interfered with the heatsink which had two running nubs that helped center the heatsink onto the cpu. since the pad ran over these two nub rails it didn't allow the heatsink to seat properly .. thus explaining why so many people are having this problem. overheating.
