CPU Temp, Fan Speeds, Mainboard Voltages, GPU Sensors and Hard Disk Temperatures of a PC

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 / 8 / 8.1 / 10 and any x86 based Linux operating systems without installation.

Latest News

Release Version 0.1.29 Beta

Added multi-CPU support and improved reading of CPU core temperatures. Added support for the latest Intel 6-core CPUS. Added basic support for the ITE IT8712F super I/O chips. Rewritten the T-Balancer code to use the FTDI D2XX drivers directly instead of the Microsoft .NET Serial Port. This should fix the crash problems when sending the PC to sleep state or hibernation. Changed the labels for the T-Balancer to match the official labeling used in the documentation. Added a dialog to automatically send a crash report. This should help make the Open Hardware Monitor more stable. Fixed a few problems where the Open Hardware Monitor would crash during startup.

Release Version 0.1.28 Beta

Added an option to automatically startup the Open Hardware Monitor after Windows logon using the Task Scheduler 2.0 for Windows Vista/7 or the Registry for Windows XP. Improved the fan speed reading for Winbond Super I/O chips. Fixed problems where sensors would get added and removed repeatetly in the GUI. Added a dialog for the report filename. Added additional checks to the T-Balancer code for cases where the port gets closed.

Release Version 0.1.27 Beta

Added additional checks to the ITE super I/O reading code, to reduce cases where wrong values are displayed. Changed the Intel CPU clock calculation. If no invariant Time Stamp Counter (TSC) is available, then the maximal CPU clock is estimated at start-up, otherwise it is measured in realtime.

Release Version 0.1.26.1 Beta

Fixed a bug with the AMD K8 (0Fh family) CPU core sensor offset parameter, which caused a crash of the Open Hardware Monitor.

Release Version 0.1.26 Beta

Fixed a crashing on systems with incomplete SMBIOS entries. Fixed T-Balancer Classic reading problems. Changed the system tray font to improve the display on some systems.
