SpeedFan screenshotSpeedFan is a software that monitors voltages, fan temperatures and speeds in PCs with hardware monitor chips. SpeedFan can even open S.M.A.R.T. data and display hard drive temperatures. SpeedFan is compatible with SCSI disks too. SpeedFan can even customize the FSB on some hardware (but this should be treated a bonus feature). SpeedFan can access digital temperature sensors and can adjust fan speeds accordingly, in this manner reducing noise.

SpeedFan can handle:

- nearly any number of South Bridges
- nearly any number of hardware monitor chips
- nearly any number of hard disks
- nearly any number of temperature readings
- nearly any number of voltage readings
- nearly any number of fan speed readings
- nearly any number of PWMs


  • Clear interface.
  • Charts section.


  • Not for beginners.
