SpeedFan: Monitor Fan, Voltage, & Temperature in a PC

SpeedFan is a freeware program that monitors voltages, fan speeds and temperatures in computers with hardware monitor chips (from its website). The latest version (4.32 released on Feb. 28) runs under Windows Vista's 32 and 64-bit versions. Note the author's note that this is for power users. If you use it to tweak your PC's firmware settings, you are on your own :-)
