Abstract
Examples disclosed herein relate to initializing a fan speed of a computing device using a high-water value when a pre-runtime event occurs. A management controller (MC) receives sensor data from sensors of the computing device. A fan speed of a fan is controlled using a fan control value based on the sensor data. The fan control value is monitored to determine a high-water value of the fan control value. The high-water value is stored in a location that is accessible by a pre-runtime fan control engine of the computing device. In response to a pre-runtime event, the fan speed is initialized to a speed using the high-water value.
