Thinkpad Fan Controller (tpfancontrol)

Computer fans can get quite loud when performing resource-intensive operations, and some older devices cannot increase or decrease fan speed based on the system’s temperature. If fans are running at full speed while your PC is idle, the noise can get very annoying.

Thinkpad Fan Controller is an open-source utility designed to help users of notebooks from the Thinkpad T4x (T40/T41/T42/T43) series, which lack appropriate fan control mechanisms. It enables users to manage fan speed in various ways in order to reduce noise levels.

Once launched, the program should display the current status of your notebook in regards to system temperature and fan speed. It monitors multiple sensors, showing the temperature of your CPU, GPU, motherboard and more.

You can choose from three operating modes: BIOS, Smart and manual. When using the manual mode, you can select one of the seven speed settings at any time. It is also possible to select the preferred option directly from the application’s system tray menu.

The latest command is displayed in the main window, and a complete log of temperature and fan speed data is also listed. It enables you to keep track of your system’s status and ensure temperatures do not exceed safe levels.
