SpeedFan is a program that monitors trouble, fan speeds and temperatures in computers with hardware monitor chips. The device can even access S. M. A. L. T. info and show hard drive temperatures. It supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this would be regarded as a bonus feature). SpeedFan can access digital temperature sensors and can modify fan speeds accordingly, thus reducing noise. We recommend downloading this great benchmark tool for Windows PC. The app can find almost any hardware monitor nick connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc. ), a subset of the I2C protocol) and works fine along with Windows 9x, ME, NT, 2000, 2003, XP and Windows Vista.
