SpeedFan is a freeware program that monitors fan speeds and temperatures in computers with a known monitoring chip. Its main feature is that it can control the speed of the fans according to the temperatures inside your pc, thus reducing noise and power consumption. Currently the only recognized (and useful) chips are WINBOND W83782D, which is found in ABIT BP6, and WINBOND W83627HF. If you've got any other motherboard with the same chip, this program is for you. What's New?

added full support for SIS635, SIS645, SIS735, SIS740 and SIS745. This means, for example, that you can read values from your ASUS P4S333 :-)

added support for FSB changing. Currently there are only a few motheboards and PLLs that are supported. On my ABIT BP6, LUCKY STAR 6LX2 and ECS K7S5A it's working pretty fine :-)

WINBOND W83791SD is now properly detected, thus avoiding detection of unknown chips at the same address

those two buttons in the CONFIG dialog should now properly show even with large fonts

added context-sensitive help (available pressing F1) which includes the tutorial

the installer/uninstaller now removes every trace from both the HD and the registry

added some new code to better reset Intel SMBus

added some tips that can be disabled after their first appearance

added preliminary ADM1024 support (please, send reports)
