For SpeedFan 4.49Publisher's description


SpeedFan is a System Utilities software developed by After our trial and test, the software is proved to be official, secure and free. Here is the official description for SpeedFan:

BS Editor: SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with Hardware Monitor chips. SpeedFan can even access S.M.A.R.T. info for those hard disks that support this feature and show hard disk temperatures too, if supported. SpeedFan supports SCSI disks too. 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 digital temperature sensors, but its main feature is that it can change fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your pc, thus reducing noise.

SpeedFan monitors temperatures, through available hardware monitor chips which expose their temperature sensors connected to different places inside your computer, and, according to your setup, does its best to keep them at your desired value. You can even change a fan speed according to the temperature of your hard disk. When choosing parameters for the minimum and maximum fan speed, try to set them by hand (disable all the VARIATE FANs checkboxes) and listen to the noise.

When you hear no noise from the fan then you can set that value as the minimum fan speed for that fan. I suggest using 100 as the maximum value, unless you hear a lot of noise from it, in which case you might reduce the maximum speed to 95 or 90. Obviously, nothing says that you can't set 60 as your maximum value and, sometimes, I myself set it that way. Consider that when the Warning temperature is reached, the program sets the fan speed to 100, whichever maximum speed you set.

SpeedFan can:

handle almost any number of South Bridges
handle almost any number of hardware monitor chips
handle almost any number of temperature readings

handle almost any number of voltage readings
handle almost any number of fan speed readings
handle almost any number of PWMs.
