Abstract
Acoustics management at an information handling system provides reduced acoustic noise with limited performance impact by dynamically changing power dissipation as a function of cooling fan speed and ambient temperature so that preemptive power restrictions prevent excessive thermal conditions that lead to excessive cooling fan speeds and associated acoustics. A maximum cooling fan speed of less than an available maximum is set and maintained by reducing power dissipation unless power dissipation reaches a minimum, after which the minimum power dissipation is maintained and cooling fan speed is allowed to increase.
