SpeedFan 4.33

By Almico  (Freeware)
User Rating

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 and show hard disk temperatures.

SpeedFan supports SCSI disks too. SpeedFan can even change the FSB on some hardware (but this should be considered a bonus feature).

SpeedFan can access digital temperature sensors and can change fan speeds accordingly, thus reducing noise.

SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus (System Management Bus (trademark belonging to SMIF, Inc.), a subset of the I2C protocol) and works fine with Windows 9x, ME, NT, 2000, 2003, XP and Windows Vista. It works with Windows 64 bit too.

SpeedFan can handle:

  • almost any number of South Bridges
  • almost any number of hardware monitor chips
  • almost any number of hard disks
  • almost any number of temperature readings
  • almost any number of voltage readings
  • almost any number of fan speed readings
  • almost any number of PWMs

4.33 - completely rewritten the detection and the identification strategy of ITE IT871xF
chips (fan readings are now ok)
- xAP support is now properly reenabled between sessions
- fixed context sensitive help (F1 key) on Windows Vista
- enabled, if needed, the SMBus on Intel ICH7 and ICH8-M
- added several checks to CPU usage routines, fixing a nasty issue where an error
window appeared once every second

- added full support for Intel ICH9 SMBus
- added full support for nVidia MCP55 SMBus
- added sull support for ADT7475
- added nVidia Control Panel access to read video card temperatures
- supported the IT8716F and the IT8718F hardware monitor at unusual addresses
- added some SMB scan exceptions for Compal 08A0
- SMBus address $15 no longer scanned on AOpen i975Xa-YDG
- fixed an issue that caused the DFI LP UT NF4 SLI-DR Venus to power off on program
- added support for Fintek F71872F voltage readings
- IT8712F-J now uses two undocumented FAN DIVs
- speeded up Asus M2N32-SLI DELUXE program startup
- added detection of an unknown Fintek chip (to avoid false detection of other
sensors at the same address)
- W83627EHF and W83627DHG now properly show SMARTFAN III in CONFIGURE / ADVANCED
- W83627EHF and W83627DHG can now change PWM TYPE from PWM to DC in CONFIGURE /
