Mechanical Engineering : News: "Department of Mechanical Engineering, Stanford University
Have you noticed that buying a new computer with higher speed (GHz) does not necessarily mean that it will run faster than your old computer? One reason for this is that faster microprocessors generate more heat, and are often forced to slow down when they become too hot. A related problem is that microprocessor heat sinks, such as fin arrays and heat pipes, are orders of magnitude larger than the silicon chip and are continuing to grow in size. These 'low-tech' bulky heat sinks are crowding away memory, video, and power-delivery components, increasing signal delays among chips and limiting the system speed."
