What is SpeedFan
SpeedFan 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.

News
SpeedFan 4.41 Beta 5 is online!
 
Added support for new CPUs, improved startup speed, added support for external USB enclosures with Cypress chipsets, improved UI reporting about hard disk SMART data, added full support for Intel 5 Series and Intel 3400 Series SMBus, fixed a typo in CONFIGURE dialog, improved Tjmax identification for Core i3, i5 and i7, added full support for Fintek F71889F, fixed CONFIGURE / EVENTS OK button glitch and speeded up program startup on Asus P5N-D.
New hard disk database is online!
 
SpeedFan's online in-depth hard disk analysis now uses an updated revision of its internal database containing the model for each known hard disk. Currently there are 2684 known hard disk models. The latest hard disks are included in the db and all the models have been updated. This means, for example, that new hard disks now properly inform about their "Power On Hours Count" taking into consideration the real values reported by the end users.
SpeedFan 4.40 Final is online!
 
Winbond W83667HG support has been greatly improved and now it changes fan speeds very well on several motherboards. CPU identification has been greatly improved too and now all of the Tjmax values published by Intel should have been implemented. Refinements, improvements and bug fixes were applied, as usual. Both the installer and the executable are now digitally signed with my company's (SOKNO S.R.L.) certificate.
Revamped web site.
 
The web site now uses DHTML and Javascript. I hope that you will enjoy a better surfing experience. I performed usability tests under all major browsers. What's more important, the web site is still accessible using W3M or LYNX under a text only environment :-)

How fan speed changing works
SpeedFan monitor temperatures from several sources. By properly configuring SpeedFan, you can let it change fan speeds based on system temperatures. 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 to use 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. You can set, say, 60 as the 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, whatever maximum speed you selected. 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 configure on which fan every temperature should rely. On my system, TEMP1 and TEMP3 are both influenced by FAN1.

A few numbers...
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
Disclaimer
This program is aimed at the power user. At those who know what they're doing. I've known of no real problem caused by SpeedFan, but may be it's due to the fact that once it made the PC explode and the user disappeared in the blast, thus being unable to report :-) Anyway: SpeedFan can be extremely useful, but you should first watch its behavior before setting and forgetting it.
Feedback
You can contact me at alfredo [at] almico.com if you've got any question or suggestion or discover any strange behavior. I'd appreciate an e-mail from those of you who try and find useful my program. Just a line of text will do.
Thanx for your attention.
