A question that has always bothered me was how do Mac Laptops stay cool. This is because as some of you know that one of the by products of using a Processor is heat being created. Normal computers use Heat sinks that increases the surface area of the CPU. From the Heat sink the heat is then discharged out of the computer from various vents. How do Mac Laptops manage to do this with the Unibody design and no vents. Do they use the entire body of the computer as a heat sink or something.
