Abstract
An electronic system has at least two fans such as a first fan and a second fan. The first fan is controlled (e.g., on/off, speed) in response a system parameter (e.g., temperature, system operational state). Preferably, the second fan is controlled dependent on the operation of the first fan. The electronic system may be a computer system. In this case, the first fan preferably is a CPU fan and the second fan is a chassis fan.
