SpeedFan 4.45

Almico - 2.01M (Freeware)

Publisher's description

SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access S.M.A.R.T. info for those hard disks that support this feature and show hard disk temperatures too, if supported. SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature).

At the lowest level, SpeedFan is an hardware monitor software that can access digital temperature sensors, but its main feature is that it can change fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your pc, thus reducing noise.

SpeedFan can:

  • handle almost any number of South Bridges
  • handle almost any number of hardware monitor chips
  • handle almost any number of temperature readings
  • handle almost any number of voltage readings
  • handle almost any number of fan speed readings
  • handle almost any number of PWMs
