How would you like to be able to control your temperature of your PC to avoid over-heating? SpeedFan is freeware program that allows user to monitor fan speeds, temperatures and even voltages in computers, equipped with hardware monitoring chips. In addition, SpeedFan also could access S.M.A.R.T. information on the hard disks (provided they supports this feature) to display its temperatures too.

Although SpeedFan is a hardware monitoring application, the most fascinating part is that it could allow you to control the speed of the fans (depending on the type of sensor chip used), in relative to the temperature inside your PC, thereby reducing noise and power consumption.

Most Winbond sensors and ASUS AS99127F support fan speeding modification. Some other motherboards from MYSON, ANALOG DEVICES, NATIONAL SEMICONDUCTORS and ITE should also make use of available pins.

Finally, SpeedFan can be minimised into the system tray, to avoid congesting in the task bar, working at the background. It is also compatible with Motherboard Monitor. If you realised that your motherboard has a chip that allows you to modify the fan speeds, give this SpeedFan 4.26 a try.
