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.
