  • Publication number: 20240019913
    Abstract: Temperature regulation at one or more modules of an information handling system is challenging due to a large number of sensors from which data is to be read, to a lack of information from which the temperature of the module or associated temperature tolerances can be determined, or both. The disclosure obviates reliance on data derived from sensors and does not rely on temperature tolerance data to regulate a temperature at a module. Access data is obtained that includes a number of accesses to the module, a time at which each access of the number of accesses occurs, or both. A temperature pattern is derived, based on the access data, and that corresponds to a temperature profile of the module. Open-loop control of a cooling device is initiated, based on the temperature patterns, to regulate a temperature of the module, a temperature profile of the module, or both.
