SpeedFan is a powerful tool designed to monitor and control computer hardware, especially the fan speeds and temperatures. Developed by Alfredo Milani Comparetti, it provides users with detailed insights into the system's health and performance. SpeedFan reads the temperature sensors on various components such as the CPU, GPU, and hard drives, offering real-time data to help prevent overheating and hardware damage.

One of the standout features of SpeedFan is its ability to adjust fan speeds based on system temperatures. This dynamic control helps maintain optimal cooling efficiency while minimizing noise. Users can set custom temperature thresholds and fan speed curves, tailoring the cooling performance to their specific needs. Additionally, SpeedFan supports S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) for hard drives, enabling early detection of potential drive failures.

The software also offers advanced logging capabilities, allowing users to track temperature and fan speed data over time. This historical data can be crucial for diagnosing intermittent issues or understanding long-term trends. With its comprehensive feature set and customizable options, SpeedFan is a valuable tool for anyone looking to optimize their system's cooling and ensure reliable operation.
