Fan Control is a highly customizable fan controlling software for Windows that lets users manage CPU, GPU, and system cooling through custom curves and profiles.
The tool addresses the need for fine-grained control over system cooling without relying on BIOS defaults or manufacturer software. It works by reading temperature data from multiple sources including CPU, GPU, motherboard, and storage devices, then applying user-defined fan curves to control PWM fan speeds. Users can create and save multiple profiles, mix curves and sensors together using functions like max, min, and average, and apply advanced tuning parameters such as response time, hysteresis, and calibration avoid points to prevent fans from running at speeds that cause rattling or noise.
Fan Control suits users who want precise thermal management beyond what their system firmware provides. It works well for enthusiasts building custom cooling setups, users with multiple fans requiring coordinated control, and anyone seeking to reduce noise while maintaining safe temperatures. The tool offers a guided setup process for first-time users and includes a graph-based fan curve editor for visual configuration. It can run as a Windows service on boot without requiring a user session, making it suitable for always-on systems.
The project maintains an active release cycle with regular updates introducing new features and refinements. Development shows responsiveness to user needs, as evidenced by recent additions like the service startup capability and calibration avoid points feature.
