Too many features nowadays require privilege elevation thus I chose to make it mandatory.
  • Beta 4 allows fan control (verified) with W83667HG and W83667HG-B, restores full access to ATI southbridges, improves PWM control with IT8720F, adds full support for W83627DHG-P and is much faster at start. A lot of other fixes and improvements.
  • SpeedFan.exe is now digitally signed using my company's (SOKNO S.R.L.) certificate.
  • This time the beta comes with a full installer, needed to upgrade the device driver.

New in SpeedFan 4.43 Beta 2 (Dec 20, 2010)

  • This beta uses a completely new driver. It properly updates ACPI temperatures on all systems (including laptops), accesses Nuvoton W83627DHG-P, no longer reads SMART Error Log Reporting data on program start (thus reducing incompatibilities), fixes Fintek F71858 support at unusual addresses and requires administrative privileges on program start.

New in SpeedFan 4.41 Beta 9 (Apr 16, 2010)

  • Intel QST 1.x support is now fully verified and full control over fan speeds is available. There are some other minor fixes too. We are quickly approaching the final stage for 4.41.

New in SpeedFan 4.41 Beta (Mar 16, 2010)

  • Added support for new CPUs. Please, send me reports from your Intel Core i3, i5 and i7. Added an option to greatly improve startup speed (look in CONFIGURE / OPTIONS and uncheck "Do SMART Summary Error Log on startup"). The UI now properly updates SMART data ablout the currently selected hard disk, including SHORT and EXTENDED TEST status. Added support for external USB enclosures using Cypress chipsets. Now you should be able to investigate those hard disks as if they were internal ones. In order to run this beta, simply install SpeedFan 4.40, then replace the EXE and then run SpeedFan as usual.
  • Please, use the SEND REPORT facility on the INFO tab to help me to evaluate the improvements I coded.
  • Tool to read ACPI TABLES 1.08 (24 jul 2006)
  • This program reads ACPI tables from your computer. There is no secret in them and no sensitive data is trasmitted. Your reports will help me to better support your hardware. Reports from notebooks and branded computers will be greatly appreciated. In order to run this tool, you simply need to have the latest SpeedFan installed. This tool is safe to run.
  • Version 1.08 removes a range check error that the compiler produced with no real reason.
  • Program to attempt to set AAM on hard disks that support it 1.01 (15 dec 2004)
  • This software tries to understand which OS and which drivers do support the relevant calls that need to be done in order to set AAM (Automatic Acoustic Management) on modern hard disks. It works only on NT class operating systems. I'm not sure if it works on NT too, but it works for sure on Win2K. Unzip, run and then use the integrated facility to send me the report. Please, send me reports even from systems where it doesn't seem to work.
  • Version 1.01 now properly identifies hards disks where AAM is available, yet disabled, and goes on with the test.
  • Program to access SCSI HD temperature and reliability data 1.13 (18 feb 2004)
  • Even if, since version 4.21, SpeedFan includes full support for SCSI drives, this tool is still useful as it allows me to see more data from SCSI drives. With the help of your reports I can try to find and show new info about your SCSI drives. This tool never caused any harm to any system and its low level code was included in the mainstream release of SpeedFan.

New in SpeedFan 4.40 Beta 3 (Aug 24, 2009)

  • SpeedFan 4.40 beta is online! Winbond W83667HG support has been greatly improved and preliminary tests show that on several Asus boards now more fans (including CPU's) can be controlled using SpeedFan. Let me know your experience. CPU identification has been greatly improved too and now all of the Tjmax values published by Intel should have been implemented. I need your tests and reports.
  • Don't forget that you can upload your configuration by using this link. I would really appreciate if experienced users with nicely working configurations could find 30 seconds to upload their configurations to help other users.

  • Tool to read ACPI TABLES 1.08 (24 jul 2006)
  • This program reads ACPI tables from your computer. There is no secret in them and no sensitive data is trasmitted. Your reports will help me to better support your hardware. Reports from notebooks and branded computers will be greatly appreciated. In order to run this tool, you simply need to have the latest SpeedFan installed. This tool is safe to run.
  • Version 1.08 removes a range check error that the compiler produced with no real reason.
  • Program to attempt to set AAM on hard disks that support it 1.01 (15 dec 2004)
  • This software tries to understand which OS and which drivers do support the relevant calls that need to be done in order to set AAM (Automatic Acoustic Management) on modern hard disks. It works only on NT class operating systems. I'm not sure if it works on NT too, but it works for sure on Win2K. Unzip, run and then use the integrated facility to send me the report. Please, send me reports even from systems where it doesn't seem to work.

With the help of your reports I can try to find and show new info about your SCSI drives. This tool never caused any harm to any system and its low level code was included in the mainstream release of SpeedFan.
