    Abstract: The described embodiments relate generally to control of rotational components in a computer system. In one embodiment, the rotational component includes a cooling fan assembly, the cooling fan assembly being controlled in accordance with resonant frequency avoidance data. The resonant frequency avoidance data being characteristic of the computer system such that when the cooling fan assembly operates in accordance with the resonant frequency avoidance data, the cooling fan assembly does not operate at a fan speed that is coincident with a natural resonant frequency of the computer system.

    Abstract: The described embodiments relate generally to control of rotational components in a computer system. In one embodiment, the rotational component includes a cooling fan, the cooling fan being controlled in accordance with data tailored to reduce the acoustic noise produced by the cooling fan. In one embodiment, the cooling fan is operated with non-uniform pulse width modulated signals. The non-uniform pulse width modulated signals can be a function of desired rotation speed and can include fundamental and harmonic components.
