Editorial Review of SpeedFan
Note: This review addresses v4.33 of the
software.
This is a must-download for serious overclockers. While SpeedFan
touts itself as a monitor for your system's temperature and fan
speed, the real reason it's worthwhile is that it lets you easily
overclock your PC and then adjust the fan speed so it doesn't
overheat.

Description of SpeedFan
SpeedFan 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, Vista and Windows 7. It works with Windows 64 bit too.
