Open Hardware Monitor is a free and open-source hardware monitoring tool that helps users track the health and performance of their computer. It monitors key system metrics such as CPU temperatures, fan speeds, voltages, clock speeds, and system load. The software supports many hardware monitoring chips commonly found on modern motherboards. It can also read Intel and AMD processor temperature sensors, GPU sensors from ATI and Nvidia cards, and SMART hard drive temperatures. Users can view monitored values in the main window, system tray, or a customizable desktop gadget. Open Hardware Monitor runs on 32-bit and 64-bit Windows systems as well as x86-based Linux operating systems without requiring installation.
