SpeedFan is a 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.
At the lowest level, SpeedFan is an 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 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
Changelog :-SpeedFan 4.34

- added native nVidia video card (up to, but excluding 8xxx) internal temperature reporting
- added full support for SMSC SCH5307
- added full support for F8000 temperatures and fan speeds
- added full support for SMSC EMCT03
- added full support for WINBOND W83793G, including ADVANCED options
- added support for Fintek F71782F hardware monitor at unusual addresses
- added support for Winbond W83627DHG at unusual addresses
- added support for ITE IT8726F hardware monitor at unusual addresses
- added support for a new stepping of the Andigilog aSC7621
- Winbond W83791D properly handles higher fan divisors for fan1, fan2 and fan3 and shows fan4 and fan5 too
- added SMSC LPC47M192 FAN DIVISOR settings in CONFIGURE / ADVANCED
- added full PWM support to SMSC LPC47B397, including settings in CONFIGURE / ADVANCED
- CONFIGURE now allows to go as low as -60C when selecting the DESIRED and WARNING levels to let users of the RELATIVE Intel Core temperature reading properly configure SpeedFan
- improved DDR2 memory module size detection
- added preliminary DDR3 identification
- new icon by Bengt Strom
- fixed an issue where Intel Core temperatures on multi core systems reported the same temperature for all cores
- improved Tjunction detection for Intel CORE temperatures (you might no longer need the temperature offset in CONFIGURE / ADVANCED)
- fixed crash on several DFI motherboards
- fixed the detection of older revisions of the ITE IT8705F
- restored the correct clock speed after resume from hibernation
- rewritten the logic of the usage of a synchronizer in the thread that reads CPU usage (this will fix the SpeedFan not exiting issue)
- address $2E on DFI motherboards is no longer scanned if the motherboard model starts with LP. If you have one of these models and you know that there should be a valid chip at that address, send me a SEND REPORT (INFO tab) with some NOTES
- fixed ADT7475 temperature readings when in offset 64 mode
- fixed a bug when changing the type of data to be charted
- mails sent by SpeedFan now properly separate headers and the body with a blank line
- fixed an issue with SUN 2864 motherboard
