How to Control Mac Mini 5,2 CPU Fan Speed on Ubuntu 24.04
Users running Ubuntu 24.04 on a Mid 2011 Mac mini 5,2 can manage CPU fan speeds using the applesmc and mbpfan tools. The Linux applesmc driver exposes Intel Mac temperature sensors and fan controls through the sysfs interface, allowing manual or automated speed adjustments. mbpfan version 2.4.0 is available as a standard package in Ubuntu 24.04 and links fan speed to CPU temperature readings from coretemp. Users can configure temperature thresholds and fan speed limits in the mbpfan configuration file based on values reported by their specific hardware. Leaving the fan in manual mode at low RPM is flagged as a risk, since it prevents the fan from responding to increased CPU or GPU load.
