Open Hardware Monitor is a Windows program for viewing data from all temperature sensors in the computer. Additionally, you can access information about the current speed of system fans. Real time CPU and GPU clock values are available as well.

System information

With the help of this software users are able to keep track of important sensor data. It is possible to monitor CPU voltage values, fan speeds and component temperatures. There is support for both Fahrenheit and Celsius measurement units.

Similar to MotherBoard Monitor, you can view the current clock speed of every individual processor core. The amount of free disk space on all connected storage devices is included as well. Moreover, detailed GPU information is provided.

The File menu lets users configure the types of data that will be displayed in the main window. Available options are mainboard, CPU, RAM, graphics card, fan controllers and hard disk drives.

Logging

There are instruments for saving all sensor values to a CSV file with a predefined interval. This functionality is helpful for diagnosing and troubleshooting various technical issues.
