What is SpeedFan?

SpeedFan is software that can read temperatures, voltages and fan speeds of computer components. It can change computer fan speeds depending on the temperature of various components. The program can display system variables as a chart and as an indicator in the system tray. Fully configurable user events can be defined to execute specific actions based on system status. SpeedFan also monitors S.M.A.R.T. readings for EIDE, SATA and SCSI hard disks. Starting with version 4.35, SpeedFan fully supports Areca RAID controllers. SpeedFan offers a feature named "in-depth online analysis" that compares your hard disk's S.M.A.R.T. data to a comprehensive database with statistical models of every known hard disk allowing early detection of potentially degraded hard disks. Full text messages inform the user of specific situations and problems, as if a human expert had looked at the data.
