BleepingComputer Review:

SpeedFan allows you to the monitor the temperature and fan speeds of various components of your computer.  This allows you to fine-tune the temperature of your components by creating custom settings that increase the fan speed when a particular temperature is reached.

For those who want complete control over their computer and components, SpeedFan is an important part of your toolkit.  Using SpeedFan you can quickly view or log the temperature of various components in your computer.  Using this information you can then fine-tune the speed of the fans in your computer to provide the best ventilation and cooling for your components.

SpeedFan currently supports the following types of sensors on a variety of different motherboard and computer components:

• almost any number of South Bridges
• almost any number of hardware monitor chips
• almost any number of hard disks
• almost any number of temperature readings
• almost any number of voltage readings
• almost any number of fan speed readings
• almost any number of PWMs

Company's Description:

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, consistently showing internal data that can be used to diagnose current and future hard disk failures. This is known as S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). At the lowest level, the SpeedFan hardware monitor software can access digital temperature sensors, but its main feature is its ability to control fan speeds according to the temperatures inside your PC, thus reducing noise.
