The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer.

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.

Core Temp is a compact, no fuss, small footprint program to monitor CPU temperature.

iStat is a series of system monitor apps. It's available in different versions: iStat Menus, iStat for iOS and iStat Server as a companion application to the iStat for iOS app that lets you remotely monitor your computers (free for Windows and Mac).

Real Temp is a temperature monitoring program designed for all Intel single Core, Dual Core, Quad Core and Core i7 processors. Each core on these processors has a digital thermal sensor (DTS) that reports temperature data relative to TJMax which is the safe maximum operating core temperature for the CPU. As your CPU heats up, your Distance to TJMax will decrease. If it reaches zero, your processor will start to thermal throttle or slow down so maximizing your distance away from TJMax will help your computer run at full speed and more reliably too. »

fancontrol is a shell script for use with lm_sensors. It reads its configuration from a file, then calculates fan speeds from temperatures and sets the corresponding PWM outputs to the computed values.

Motherboard Monitor is a utility designed by Alexander Van Kaam for Microsoft Windows that provides live information about the state of a motherboard and other hardware, including temperatures, voltages, fan speeds, and more.

Hardware sensors monitor utilizes sensor chips on smart motherboards to track system and CPU core temperatures, voltages and cooling fans. By quickly catching an overheated computer, you can prevent disasters such as system instability or damage. The program is resource friendly, resides quietly in the system tray, and continually monitors the various parameters. By clicking its icon, you'll view real time values for each component. Hmonitor supports all modern Windows versions: Windows 7, Vista, 2008, XP, 2003, 2000 ,NT4, including X64 editions. »
