In order to adequately but not excessively or unnecessarily cool heat generating electrical components and decrease the noise produced by fans used to cool the heat generating electrical components in an electrical hardware system, an environmental controller controls the speeds of the fans using at least two temperature sensors. In one example, a first temperature sensor measures a hotspot component temperature and generates a hotspot component temperature value, and a second temperature sensor measures an air inlet temperature and generates an air inlet temperature value. The environmental controller controls the speeds of the fans based on the difference between the measured hotspot component temperature value and a target hotspot component temperature value calculated based on the measured air inlet temperature value and a predefined function.
