Open Hardware Monitor

The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer. Open HWM app supports most hardware monitoring chips found on today's mainboards. The CPU temperature can be monitored by reading the core temperature sensors of Intel and AMD processors.

Open Hardware Monitor is a free and open-source software application designed to monitor various hardware components of your PC in real-time. It provides detailed information about your CPU, GPU, hard drives, motherboard, and other peripherals. Developed primarily for Windows-based systems, this tool offers a comprehensive view of your system's vital statistics, enabling users to monitor temperature, voltage, fan speeds, and utilization rates.

The sensors of ATI and Nvidia video cards as well as SMART hard drive temperature can be displayed. The monitored values can be displayed in the main window, in a customizable desktop gadget, or in the system tray. The free OHM software runs on 32-bit and 64-bit Microsoft Windows XP / Vista / 7 / 8 / 8.1 / 10 / 11 and any x86 based Linux operating systems without installation. The Open OHM software publishes all sensor data to WMI (Windows Management Instrumentation). This allows other applications to read and use the sensor information as well.
