SpeedFan 4.39 Beta 7

SpeedFan 4.39 Beta 7 is a powerful tool that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips.

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. It is suggested 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. 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.

Major Features:

1. Access S.M.A.R.T. info and show hard disk temperatures.
2. Supports SCSI disks too.
3. Change the FSB on some hardware (but this should be considered a bonus feature)
4. Access digital temperature sensors and can change fan speeds accordingly, thus reducing noise.
5. 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)
6. Works fine with Windows 9x, ME, NT, 2000, 2003, XP and Windows Vista. It works with Windows 64 bit too.
7. Show its user whats really going in their machine. When minimized, a temperature reading is showed on the button right of the desktop.
8. When Speedfan is in an open window you can see a whole lot more. From Fan speed to total voltage, you can view any and all of the current fan.

Enhancements:

• SMART hard disk access: Now it works even with drivers that use SCSI MINIPORT
• Non-destructive hard disk test 

Requirements:

• Windows 9x, ME, NT, 2000, 2003, XP
• Windows Vista.
• Windows 64 bit
