SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips. SpeedFan can even access SMART info for those hard disks that support this feature and show hard disk temperatures too, if supported. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is a hardware monitor software that can access temperature sensors, but its main feature is that it can control fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your PC, thus reducing noise and power consumption. NOTE:This version includes a lot of new features. Full support for INTEL CORE DUO internal temperatures, for Andigilog aSC7621 and for Fintek F71882F has been added, including advanced configuration options. Another great new addition is xAP support, which allows you to publish temperatures and fan speeds using this pretty new and interesting protocol. Not to mention that the driver that allows SpeedFan to fully support even Windows Vista 64 bit is now signed with my digital certificate.
