SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips.
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.
" One last word should be said regarding the USE FAN x listbox. In my pc, more than one temperature changes when a fan runs faster. You can say on which fan every temperature should rely. On my system, TEMP1 and TEMP3 are both influenced by FAN1." ...author.
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
Authors Note:
"SpeedFan is an extremely powerful tool. It can help you a lot to find the reasons for an unpredictable reboot or for a failing hard disk. It can tell you whether you are likely to experience temperature related issues and can help you to greatly reduce the noise at work or while watching a movie. But this great power requires access to a lot of resources on your motherboard and it might be that your hardware does not like such kind of access. SpeedFan is used worldwide since 2000 and there are so many happy users out there, but you should always remember that no program can be perfect and that I can't be held responsible if SpeedFan causes any damage to your system.".......Alfredo Milani Comparetti
