SpeedFan automatically searches your computer for informative chips: the hardware monitor chips. SpeedFan can display voltages, fan speeds and temperatures. On rare occasions, the BIOS doesn't activate such features. SpeedFan tries to enable them as long as this is a safe thing to do. Not only the motherboard is searched, but also some video cards and almost every currently sold hard disk. SpeedFan can access status info from EIDE, SATA and even SCSI drives -
