Thinkfan UI

Small and simple application for controlling fan speed on IBM/Lenovo ThinkPads, it can also monitor CPU temp and fan RPM.

This is a complete rewrite of scientifichackers/thinkfan-control-gui using PyQt5 PyQt6.

It is written for Linux only. For Windows, see speedfan.

How it Works?

• Parses sensors command to show CPU temp
• Modifies /proc/acpi/ibm/fan to change fan speed

CLI Arguments

• --no-tray disables tray icon
• --hide hides main window on start
