SpeedFan4.52

SpeedFan reads the values reported by a computer’s hardware monitoring chips and presents them for inspection. It tracks system voltages, fan speeds, and temperatures, giving users a direct view of selected hardware conditions. By collecting these readings in one program, it helps reveal how the computer’s monitored components are operating at a given time.

The program is useful when checking temperature behavior, observing fan activity, or reviewing voltage readings during routine maintenance and hardware monitoring. It is intended for Windows users whose computers contain compatible monitoring chips and who want to follow the measurements those chips provide. SpeedFan focuses on reporting these hardware values rather than managing unrelated system information.

Alfredo Milani Comparetti publishes SpeedFan, currently at version 4.52 for Windows on x86 architecture. Its readings depend on the presence of compatible hardware monitor chips in the computer, so the available measurements are determined by the hardware those chips can monitor.
