Looking at your sensors output, the MediaTek WiFi card (mt7925) is reportin= g a temperature of +86.0=C2=B0C. Modern thin-and-light laptop firmware (Embedded Controller) often monitors multiple sensors (CPU, NVMe, WiFi, and skin sensors). If the WiFi card or NVMe SSD is hot, the BIOS/EC will keep the fan spinning at a low RPM (like 2100 RPM) to cool the chassis, even if the CPU = is idling at 39=C2=B0C. You can inspect which ACPI thermal zone is triggering the active cooling by running: > tail /sys/class/thermal/thermal_zone*/type > tail /sys/class/thermal/thermal_zone*/temp Since the platform profile driver is now working correctly, you should try switching it to quiet or low-power (if available on your model) using powerprofilesctl set quiet. This is the official way to tell the EC/BIOS to= use a quieter fan curve and adjust the trip point thresholds. --=20 You may reply to this email to add a comment.
