hello xcom
unfortunately the fan speed is controlled by the hardware not software so upgrading code will not help.
Here's some information from PLMSimilar to X440, X430 fans are controlled by hardware, and software does not have any control on fan speeds.
Based on the temperature sensor readings, fan speed is selected accordingly to keep the switch from over-heating.
Thanks
