SpeedFan
SpeedFan is an advanced system monitoring tool
SpeedFan lets you take a deeper view at the status of your computer. Almost every computer includes support for hardware monitoring. Accessing digital temperature sensors is really useful. If you are trying to figure out why your PC hangs when under heavy load or after some hours of usage, SpeedFan might help you find the real cause. Very often it is a poor power supply, or an improperly installed heatsink that lead to behaviours that we tend to associate (incorrectly) with errors from the operating system. 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 -
