SpeedFan is asystem monitor forMicrosoft Windows that can read temperatures, voltages and fan speeds of computer components.[3] It can changecomputer fan speeds depending on the temperature of various components.[1][4] The program can display system variables as charts and as an indicator in thesystem tray.[1][4][5]Fully configurable user events can be defined to execute specific actions based on system status[6]
SpeedFan also monitorsS.M.A.R.T. readings for EIDE, SATA and SCSI hard disks. Starting with version 4.35, SpeedFan fully supportsArecaRAID controllers. Version 4.38 added full support forAMCC/3ware SATA andRAID controllers.[1]
SpeedFan offers a feature named "in-depth online analysis" that compares the hard disk's S.M.A.R.T. data to a database with statistical models of hard disks allowing early detection of potentially degraded hard disks.[7] Messages inform the user of specific situations and problems, which Almico says is “as if a human expert had looked at the data”.[1]
An extended review of version 4.46 in 2012 on the Silent PC Review website summarized, "The biggest drawback [to Speedfan] is it often takes a lot of work to properly configure", but continued, "Its highly customizable and incredibly powerful nature is unmatched by the competition and as a bonus, it's also free, lightweight and regularly updated with more features and better motherboard support."[8]The Softonic review of version 4.49 graded SpeedFan 8/10, listing it as useful, with "helpful charts to monitor performance and health", but noting that it requests administrator rights at launch, and "Can be intimidating for less tech savvy".[9]
