System and method for controlling a fan. A value may be received for controlling the fan. The value may include a first number of bits and may correspond to a linear function of temperature. A first value may be determined using a first number of bits of the value. A modification to the first value may be determined based on a second number of bits of the value. A new output value may be generated based on the first value and the modification to the first value. The new output value may correspond to a first nonlinear function of temperature. The new output value may be provided for controlling the fan.
