Some embodiments of the present invention provide a system that assures stability of the speed of a cooling fan in a computer system. During operation, a temperature of the computer system, an ambient temperature, and a current fan speed for the cooling fan are monitored. Next, a validated ambient temperature based on parameters including the temperature of the computer system, the ambient temperature, and the current fan speed is computed. Then, a control signal is generated in response to the validated ambient temperature, and the control signal is sent to the cooling fan to assure stability of the fan speed of the cooling fan.
