As computer performance increases, so does the amount of noise generated. Computer manufacturers spend huge amounts of money developing the next generation of high performance computers, without considering noise and vibration issues. As a result, quiet computers are becoming highly desirable, particularly for low noise environments such as recording studios and bedrooms. There are now numerous products available, all stating that they will significantly reduce the amount of noise generated by the computer. This paper investigates the effectiveness of different noise attenuation methods, and looks at some potential pitfalls of a quiet computer.
