The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer.
The Open Hardware Monitor supports most hardware monitoring chips found on todays mainboards. The CPU temperature can be monitored by reading the core temperature sensors of Intel and AMD processors. 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 Open Hardware Monitor software runs on 32-bit and 64-bit Microsoft Windows XP / Vista / 7 and any x86 based Linux operating systems without installation.

Installation

To install just unpack the zip archive and run OpenHardwareMonitor.exe with Administrator rights. Without Administrator rights most hardware sensors are not accessible. The application is still in Beta status, so use it at your own risk.

Release Version 0.4.0 Beta
  • Added an option to show the sensor-plot in a separate window or on the right of the tree-view.
  • Added support for saving and restoring the sensor history as shown in the plot for the last 24h.
  • Added a context menu to the plot which allows the user to configure the time window for plotting.
  • Added code to save and restore the plot sensor selection.
  • Added support for AMD family 12h (Llano) and 15h (Bulldozer) CPUs.
  • Added support for package level temperature sensors on new Intel Sandy Bridge CPUs.
  • Added support for Intel CPU power sensors (package and cores).
  • Improved the CPU load sensors. The values displayed for the load per core and the total load should now be more accurate.
  • Rewritten the SMART HDD and SSD monitoring code based on a patch by Roland Reinl. The report now contains a list of all SMART attributes with the labels as identified by the Open Hardware Monitor.
  • Added support for SMART total host writes and total host reads sensors on SSDs.
  • Further restricted the identification for Indilinx SSDs to prevent Maxtor HDDs to be identified as Indilinx SSD.
  • Added the hard drive firmware version to the report.
  • Added support for the Fintek F71889AD super I/O chip.
  • Added support for the ITE IT8772E super I/O chip.
  • Added support for fan control on the NCT677X super I/O chips.
  • Added fan control for Nvidia GPUs based on a patch by Christian Vallières.
  • Extended the identification list of mainboard manufacturers.
  • Added mainboard specific configurations for the Gigabyte Z68X-UD7-B3, ASUS P8P67, ASUS P8P67 EVO, ASUS P8P67 PRO and Shuttle SH67Hx mainboards.
  • Added a third decimal place for voltages to the displays.
  • Optimized the memory allocation behavior of the GUI.
