Abstract
A computer system and method for measuring air density in a computer chassis. The computer chassis includes a fan, an ambient air temperature sensor, and a heat-generating device with a heat sink, a heat sink temperature sensor, and a controller. The controller controls the fan speed and applies a known amount of thermal energy to the heat sink, then determines the air density from the difference in temperature between the ambient air and the heat sink. The controller may then use the air density determination to adjust the air flow rate through the computer chassis to provide a proper air flow rate for cooling.
