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.[1] The program can display system variables as a chart and as an indicator in the system tray.[1][2] Fully configurable user events can be defined to execute specific actions based on system status. As of version 4.37, temperatures in the event section must be specified in °C no matter if the display setting is for °F.
Hard disk support
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. Version 4.38 added full support for AMCC/3ware SATA and RAID controllers.
Hard disk in-depth online analysis
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.
Risks
SpeedFan crashes some systems when it is launched, possibly causing registry corruption or loss of recent changes to the registry. This can cause recently-installed programs to disappear from Add/Remove Programs, programs to no longer function correctly, or loss of operating-system stability. This problem is not unique to SpeedFan as any action that forces the computer to stop suddenly will have this potential.[3][4][5][6] This appears to be fixed now.
