The reason the fan is still spinning at 2100 RPM is that the BIOS has configured a very low active cooling thresholds (trip points). For example,= the threshold to turn on the fan at its lowest speed might be set to 30=C2=B0C = or 35=C2=B0C. Since 38=C2=B0C is above that threshold, the fan stays on. To confirm this, you can check your ACPI trip point temperatures by running: > cat /sys/class/thermal/thermal_zone0/trip_point_*_temp > cat /sys/class/thermal/thermal_zone0/trip_point_*_type Since you now have 'power-saver', 'balanced', and 'performance' profiles working, try switching to the power saver profile: > powerprofilesctl set power-saver Under the power-saver profile, the BIOS/EC should increase the temperature thresholds (e.g. from 35=C2=B0C to 45=C2=B0C or 50=C2=B0C), which should al= low the fan to turn off completely when the system is idling at 38=C2=B0C. --=20 You may reply to this email to add a comment.
