I use a FREE Program called SpeedFan to monitor the Speed
Temperature and Voltage of my Fans..

SpeedFan is a freeware 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. SpeedFan
can even change the FSB on some hardware (but this should be considered a bonus
feature). 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.
Several sensors, like Winbond's and the AS99127F support fan speed changing, as
well as others from Maxim, Myson, Analog Devices, National Semiconductor and
ITE, but the hardware manufacturer must have connected the relevant pins to
some additional, yet trivial, circuitry. This means that if you have, say, a
Winbond W83782D on a BP6 then you're ok, but not every motherboard with such an
hardware monitor chip will be able to change fan speeds. From one of the very
first hardware monitor chips that could be found in standard PCs, the National
Semiconductor LM75 (and all of its clones, like the Philips NE1617 and the
Philips NE1618 or the Maxim MAX1617) or the Analog Devices ADM1021, such chips
have been greatly improved, both in their precision and in their capabilities.
Current chips can monitor fan speeds, voltages and change fan speeds by using
PWMs (Pulse Width Modulation). Some chips can even be programmed to vary fan
speeds without any additional software intervention. If your BIOS was
programmed to setup such chips this way you can still try to use SpeedFan's
Advanced Configuration to revert to manual (software controlled) mode. Winbond
W83697HF, Analog Devices ADT7463, SMSC EMC6D102, ITE IT8712F, National LM85C
and Maxim MAX6650 are very good candidates. Some SuperIO chips include
temperature sensors too. SpeedFan can
automatically detect them and use their features. SpeedFan can find almost any
hardware monitor chip connected to the 2-wire SMBus (System Management Bus, a
subset of the I2C BUS) Serial Interface and to the ISA BUS and works fine with
Windows 9x, ME, NT, 2000, 2003 and Windows XP. It works with Windows 64 bit
too. It can be minimized to the tray and is compatible with Motherboard Monitor
5.
