SpeedFan can access digital sensors available on your pc. By acessing available hardware monitor chips,
SpeedFan can show temperatures, voltages and fan speeds. SpeedFan can show S.M.A.R.T. data from almost
evey hard disk too. Temperature sensors from almost every manufacturer are automatically detected and
accessed. Usually, the only action you need to take is to rename the readings that SpeedFan found. If
your hardware allows it and you properly configured SpeedFan, you can change fan speeds depending on
system temperatures, thus reducing overall noise.
SpeedFan lets you take a deeper view at the status of your computer. Almost every computer includes support for hardware monitoring. Accessing digital temperature sensors is really useful. If you are trying to figure out why your PC hangs when under heavy load or after some hours of usage, SpeedFan might help you find the real cause. Very often it is a poor power supply, or an improperly installed heatsink that lead to behaviours that we tend to associate (incorrectly) with errors from the operating system. SpeedFan automatically searches your computer for informative chips: the hardware monitor chips. SpeedFan can display voltages, fan speeds and temperatures. On rare occasions, the BIOS doesn't activate such features. SpeedFan tries to enable them as long as this is a safe thing to do. Not only the motherboard is searched, but also some video cards and almost every currently sold hard disk. SpeedFan can access status info from EIDE, SATA and even SCSI drives, consistently showing internal data that can be used to diagnose current and future hard disk failures. This is known as S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). At the lowest level, the SpeedFan hardware monitor software can access digital temperature sensors, but its main feature is its ability to control fan speeds according to the temperatures inside your PC, thus reducing noise.
peedFan is a program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures.
SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature).
SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise.
SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol) and works fine with Windows 9x, ME, NT, 2000, 2003, XP and Windows Vista. It works with Windows 64 bit too.
SpeedFan can handle:almost any number of South Bridgesalmost any number of hardware monitor chipsalmost any number of hard disksalmost any number of temperature readingsalmost any number of voltage readingsalmost any number of fan speed readingsalmost any number of PWMs
