SpeedFan
http://www.almico.com/speedfan.php
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).
