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

AIDA64 is a system information, diagnostics, and auditing application developed by FinalWire Ltd., that runs on Windows, Android, iOS, Windows Phone and Tizen operating systems. It displays detailed information on the components of a computer. Information can be saved to file in formats such as HTML, CSV, or XML.

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.

HWMonitor is a hardware monitoring program that reads PC systems main health sensors : voltages, temperatures, fans speed.

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

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. »

smcFanControl is the perfect application for all those Macbook owners getting burned by their hot-running Macbook.This Mac application allows you to control the speed of the fan in your MacBook so you can avoid it running hot.

Lm-Sensors is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans.

3C Toolbox is the comprehensive toolbox to save battery, tweak, tune, backup, secure and monitor any Android devices running any ROMs, any kernels.

WinBar is a free and compact program that lets you monitor your system and provides easy access to frequently used controls. WinBar will run on Windows 2000 and newer operating systems and is available in 32 and 64 bit flavors.
